TRMM Satellite Maps Japan's Record Rainfall from Tropical Storm Talas

Tropical Storm Talas formed over the western Pacific Ocean on August 25, 2011, and took a north-northwesterly route across Japan. The storm dropped heavy rain on the island, leaving floods and landslides in its wake.

The Joint Typhoon Warning Center noted that Talas made landfall in southern Japan as a strong tropical storm. Talas created most damage in the Wakayama prefecture on the Kii Peninsula. The Kii Peninsula is a mountainous area, where heavy rainfall caused mudslides and flooding.

Most of the rainfall was north and west of Talas' center, so Tokyo currently had cloudy conditions on Saturday, Sept. 4. The areas that did get rain saw record-breaking rainfall that led to flooding and mudslides. The Japanese Meteorological Agency reported that Talas brought record-breaking rainfall by dropping 65 inches (165 centimeters) of rain in 72 hours. The Japanese Meteorological Agency noted that three prefectures recorded record rainfall. According to CNN, flooding and mudslides killed 38 people, and 54 more are reported missing.

Jesse Allen of NASA's Earth Observatory at NASA's Goddard Space Flight Center in Greenbelt, Md. created a color-coded image showing rainfall totals from August 30 to September 5, 2011 using TRMM satellite data.

The image is based on data from the Multisatellite Precipitation Analysis produced at NASA’s Goddard Space Flight Center, which estimates rainfall by combining measurements from many satellites and calibrating them using rainfall measurements from the Tropical Rainfall Measuring Mission (TRMM) satellite.

The heaviest rainfall—more than 350 millimeters or 14 inches—appears in dark blue. The lightest rainfall—less than 50 millimeters or 2 inches—appears in light green. Areas with only a trace of rain appear pale yellow. Superimposed on the rainfall totals is a storm track, shown in pink.

The flooded rivers, ruined roads, and avalanches of earth not only claimed lives, but also hampered search-and-rescue efforts, The Japan Times said. The death toll from the storm was expected to rise. Meanwhile, thousands of residents remained cut off from the outside world, and authorities were attempting to rescues via helicopter.

Tropical Storm Talas Raining on Japan All Weekend

NASA's Aqua satellite captured the fringes of Tropical Storm Talas' clouds over Japan yesterday, and today, Sept. 2, NASA infrared data showed its clouds covering the big island. Talas is expected to continue bringing the big island of Japan clouds and rainfall all weekend as it moves across and into the Sea of Japan.

Tropical Storm Talas' clouds reached the southern shores of Japan on Sept. 1 and the Moderate Resolution Imaging Spectroradiometer (MODIS) on NASA’s Aqua satellite captured an image of the cloud extent.

During the morning hours (Eastern Daylight Time) Tropical Storm Talas was blanketing almost all of mainland Japan with clouds and showers.

At 11 a.m. EDT on Sept. 2, 2011, Kyoto, and Hirakata, Japan reported rainfall from Tropical Storm Talas. Talas' rainbands stretched over southern Japan and northwest into the Sea of Japan. The forecast in Kyoto calls for a slow-moving Tropical Storm Talas to affect the region through Sunday, September 4 before fully pulling away into the Sea of Japan and then moving to the northeast.

AT 11 a.m. EDT on September 2, 2011, the U.S. Navy’s Joint Typhoon Warning Center (JTWC) reported that Talas had maximum sustained winds of 50 knots (57 mph/92 kilometers per hour). Talas' center was about 185 nautical miles south-southwest of Kyoto, but because of the storm's massive size, it was almost covering mainland Japan. The center was located near 32.8 North and 134.3 East. It is forecast to continue moving to the north-northwest at 10 knots (11 mph/18 kmh).

The Atmospheric Infrared Sounder (AIRS) instrument aboard NASA's Aqua satellite provided an infrared look at Talas this morning, Sept. 2, and showed that the cloud top temperatures warmed as the storm continues to cover Japan. Warming cloud tops mean the clouds are dropping in height and strength and is typical for a landfalling tropical storm.

The JTWC described Talas as a puzzling storm: “The analysis continues to reveal an unusual upper-level pattern with an upper low over the center and anticyclonic flow around the periphery.” Different models of the storm were in poor agreement, but the JTWC forecast that Talas would likely travel northward and weaken as it passed over Japan.

Residents throughout Japan can expect to continue being affected by Talas' clouds and or rain as the slow moving tropical storm moves west-northwest, then tracks northeastward and parallel to Japan's west coast over the weekend.

NASA Sees Heavy Rainfall in Tropical Storm Talas as it Approaches Japan

The TRMM Satellite noticed heavy rainfall and high, strong thunderstorms in the northern quadrant of Tropical Storm Talas as it approaches Japan for a landfall. Because Talas is so large, even the outer bands are raining on southern Japan.

The Tropical Rainfall Measuring Mission (TRMM) satellite is a satellite that's managed by NASA and the Japanese Space Agency, the latter of which has a particular interest in the storm as it is forecast to make landfall in southeastern Japan this weekend.

TRMM can measure rainfall from its orbit high above the earth and provide heights of towering thunderstorms within a tropical cyclone. On August 31, 2011 at 7:21 p.m. EDT, TRMM revealed several towering thunderstorms even in Talas' northern edge- that were about 6 miles (10 kilometers) high. Areas of heavy rainfall peppered the TRMM satellite image in Talas' north and northwestern quadrants. In much of the rest of the storm, moderate rainfall was occurring, according to TRMM rainfall data.

On Sept. 1 at 11 a.m. EDT, Talas' maximum sustained winds were still near 55 knots (63 mph/103 kmh).It was about 375 nautical miles south of Kyoto, Japan near 29.2 North and 135.3 East. It was moving to the northwest near 6 knots (8 mph).

At 11 a.m. EDT on Sept. 1, 2011, Kyoto was already reporting light rainfall from Talas' outer bands because Talas is a large storm. The bulk of the rain and Talas' center was still far to the south. Talas will make landfall on Friday as a minimal typhoon and cross over into the Sea of Japan, where it will become extra-tropical.

NASA Sees Tropical Storm Nanmadol's Landfall, Talas Headed to Japan

Tropical Storm Nanmadol made landfall in southeastern China's Fujian Province and is now a depression, while further east, Tropical Storm Talas is still headed for Japan.

Infrared satellite imagery from The Atmospheric Sounder Instrument (AIRS) aboard NASA's Aqua satellite shows two different stories in the tropical cyclones.

AIRS captured an infrared image of Nanmadol on Aug. 31 at 1:05 EDT dissipating quickly over mainland China with a lack of high, thunderstorm clouds. Most of the remnants of Nanmadol are lower, warmer clouds.

Tropical Storm Nanmadol made landfall about 2.00 a.m. local time on Aug. 31 (2 p.m. EDT on Aug. 30), in Jinjiang city, located in the Fujian Province, (southeastern) China. Nanmadol was a tropical storm at the time of landfall with sustained winds reported near 44 mph (72 kmh). By 8 a.m. local time/China on August 31 (August 30 at 8 p.m. EDT), Nanmadol's maximum sustained winds dropped down to 25 knots (29 mph/46 kmh), and it continued to move inland at 4 knots (5 mph/7 kmh). It was located near 24.9 North and 118.7 East. It is expected to dissipate later today or tomorrow.

Agence France-Press reported that Nanmadol destroyed hundreds of homes in Taiwan earlier this week.

AIRS infrared imagery of Tropical Storm Talas late on Aug. 30 (11:29 p.m. EDT) showed the large eastern half contained strong, high, thunderstorm clouds around the center where cloud top temperatures exceed -63F (-52C).

Today, Tropical Storm Talas is still working toward a landfall. The Joint Typhoon Warning Center forecasts a landfall in southern Japan on September 2. Talas still had maximum sustained winds near 55 knots (63 mph/103 kmh), as it did yesterday.

It was located about 465 miles (748 km) south of Kyoto, Japan, near 27.3 North and 136.8 East. It was moving to the northwest at 5 knots (6 mph/XXX). Talas is still a large storm with tropical storm-force winds extending out 210 miles, making it at least 420 miles (675 km) in diameter. Talas continues to intensify as it moves northward. Talas is expected to make landfall Friday and then become extra-tropical after crossing Japan and moving into the Sea of Japan.

NASA Sees Western Pacific Tropical Storm Talas Twice as Large as Nanmadol

Tropical Storm Nanmadol is headed for landfall in China later today while Tropical Storm Talas is still days away from affecting Japan. NASA's Aqua satellite infrared imagery continues to show that Talas is much more organized than Nanmadol and twice Nanmadol's size.

NASA's Aqua satellite passed over both storms on August 30 and obtained cloud-top temperature readings of both tropical storms. Colder cloud top temperatures are more abundant in Tropical Storm Talas as it is a stronger storm, and not facing the adverse winds against Nanmadol. The wind shear battering Nanmadol is preventing convection from forming more powerful, high thunderstorms (with colder cloud temperatures).

Tropical Storm Nanmadol's maximum sustained winds are now near 35 knots and it is being battered by wind shear as it moves west across the Strait of Taiwan. The storm is about 170 miles wide as tropical storm-force winds extend 85 miles from the center. Nanmadol is forecast to make landfall in mainland China later today, August 30. At 11 a.m. EDT it was 140 miles west of Taipei, Taiwan near 24.7 North and 119.0 East.

Further east, NASA's Aqua satellite saw some impressive banding of thunderstorms around Tropical Storm Talas' center of circulation, particularly to the south. That's evident in the forecast from the Joint Typhoon Warning Center, where meteorologists expect the storm to strengthen slowly.

Talas appears to be double the size of nearby Tropical Storm Nanmadol, Talas measures about 340 miles in diameter, versus Nanmadol's 170 miles. Talas' maximum sustained winds are around 55 knots and it is moving to the north-northwest at 7 knots. Talas is currently about 560 miles south of Toyko, Japan. Talas is expected to pass over mainland Japan then become extra-tropical.

NASA's Infrared Tracking of Two Pacific Tropical Storms: Talas and Nanmadol

Infrared images from NASA's Aqua satellite have been keeping track of two tropical storms in the western North Pacific Ocean: Talas and Nanmadol. Talas appears much more organized than Nanmadol in both circulation and bands of thunderstorms. One tropical storm is headed for a landfall in Japan and the other a landfall in China.

NASA's Aqua satellite passed over both storms on August 29 and obtained cloud-top temperature readings of both tropical storms noting a difference in organization and circulation.

Tropical storm Nanmadol, also called "Mina" in the Philippines was about 125 miles southwest of Taipei, Taiwan near 23.5 North and 119.9 East today, August 29, at 5 a.m. EDT. Nanmadol had maximum sustained winds near 50 knots and was moving to the northwest near 8 knots. It is generating very rough seas, with waves as high as 23 feet.

An infrared image of Tropical Storm Nanmadol's cold clouds was taken by the Atmospheric Infrared Sounder (AIRS) instrument on NASA's Aqua satellite, Aug. 29 at 1:17 a.m. EDT. Nanmadol is a large storm as evidenced in the satellite image as the western edge of the storm is already over mainland China, and the eastern edges are over Taiwan and Luzon, Philippines. There were a couple of strong bands of thunderstorms south of the center of circulation, where cloud top temperatures exceeded -63 Fahrenheit (-52 Celsius).

Nanmadol provided deadly in the Philippines by killing 14 people in Northern Luzon over the weekend, according to GMA News. Public storm warning signals are still in effect today for the Batanes Islands of Luzon. Nanmadol passed over the island of Taiwan this weekend and is now in the Strait of Taiwan. It is forecast to make a final landfall in mainland China tomorrow, August 30.

Tropical Storm Talas is located further east in the western North Pacific and appears to have its sights on a landfall in Japan.

At 5 a.m. EDT, August 29, Talas had maximum sustained winds near 55 knots. Talas was 715 miles south of Tokyo, Japan near 23.8 North and 140.1 East. It was moving to the north near 2 knots and generating 33 foot high waves. Talas is forecast to intensify until it approaches Japan when atmospheric conditions will again weaken it.

The AIRS infrared image of Tropical Storm Talas on Aug. 28 at 11:35 p.m. EDT shows a more organized storm. Talas appears to have an eye with good circulation surrounded by tightly curved bands of strong thunderstorms to the north, east and south of the center. By September 2, Talas is expected to make landfall in Japan's Kanto Plain, south of Toyko.

NASA Sees Super Typhoon Namadol Explode in Strength, Talas Also Strengthens

Within 24 hours Tropical Storm Nanmadol contracted and organized quickly, exploding into a Category Four Typhoon as NASA's Aqua satellite passed overhead.

NASA's Aqua satellite provided two different perspectives of this supertyphoon: a visible and an infrared. The Moderate Resolution Imaging Spectroradiometer (MODIS) instrument on NASA's Aqua satellite captured a visible image of Super Typhoon Nanmadol over the Philippines at 12:50 a.m. EDT (4:50 UTC).

The Atmospheric Infrared Sounder (AIRS) is the instrument on Aqua that took an infrared image of Nanmadol's and nearby Tropical Storm Talas' cloud top temperatures on August 26 at 12:47 a.m. EDT. AIRS infrared image revealed that the super typhoon has highly symmetrical bands of thunderstorms wrapping tightly into its eye. Nanmadol has an eye that is 18 nautical miles (21 miles/33 km) in diameter. Tropical Storm Talas, located to the northeast of Nanmadol.

At 11 a.m. EDT (1500 UTC) on August 26, Super Typhoon Nanmadol's maximum sustained winds were near 135 knots (155 mph/250 kmh) with higher gusts making it the top end of the Category four typhoon status. Category five typhoons have sustained wind speeds of greater than 155 mph (135 knots).

Nanmadol was about 585 nautical miles (673 miles/1083 km) south-southwest of Kadena Air Base, Japan and northeast of Luzon, Philippines where it was dropping heavy rainfall. Nanmadol is moving to the north-northwest at 6 knots and is generating dangerous surf with wave heights reaching 32 feet (.7 meters)!

Forecasters at the Joint Typhoon Warning Center (JTWC) expect Nanmadol to intensify further into a Category Five Typhoon then gradually weaken. Nanmadol is expected to continue skirting Luzon, passing it on August 27, then passing to the east of Taiwan on August 28 and 29. Taiwan can also expect very rough seas, gusty winds and heavy downpours as Nanmadol passes by and heads to the northwest next week.

At the same time, and much farther to the northeast, Tropical Storm Talas had maximum sustained winds near 45 knots (52 mph/83 kmh). It was located about 185 nautical miles (212 miles/ 342 km) south-southwest of the island of Iwo Two, Japan near 22.3 North and 139.8 East. It was moving to the north-northwest near 6 knots (7 mph/11 kmh) and also generating rough seas, 22 feet high (6.7 meters). The AIRS infrared data showed bands of strong convection wrapping around the northeastern edge of the center, indicating strengthening.

The JTWC forecast calls for Talas to steadily intensify over the weekend because of warm sea surface temperatures and favorable upper level atmospheric conditions. Talas is expected to take a more northerly track and pass just to the west of Iwo To over the weekend, and past Chichi Jima on Monday, August 29.

It is going to be a busy weekend in the western North Pacific Ocean with strengthening Super Typhoon Nanmadol and a strengthening Tropical Storm Talas.

NASA Satellite Sees Quick Birth of Tropical Storm Talas

Iwo To and Chichi Jima are in the projected path of the newest tropical storm that formed in the western North Pacific Ocean, and infrared NASA satellite data revealed some strong, high thunderstorms around the center of Tropical Storm Talas.

NASA's Aqua satellite passed over Talas early today, August 25, 2011. The Atmospheric Infrared Sounder (AIRS) instrument captured an image at 4:00 UTC (12:00 a.m. EDT). The image showed a very large area of strong thunderstorms south of the center of circulation that marked its intensification into a tropical storm. The Joint Typhoon Warning Center noted that the expansive thunderstorm banding from the east to the south side of circulation are characteristic of a monsoon depression.

Tropical Storm Talas strengthened quickly this morning and is currently located about 280 nautical miles south of Iwo Jima near 20.2 North and 140.6 East. It had maximum sustained winds near 40 knots (46 mph). It was moving to the north at 10 knots.

The strong thunderstorms and convection (rapidly rising air that forms the thunderstorms that make up the tropical storm) are indications that Talas is steadily intensifying. Although Talas may interact somewhat with nearby Tropical Storm Nanmadol (which is located east near Luzon, Philippines), it is still expected to continue north.
