The NASA Aqua satellite captured two distinct views of Super Typhoon Choi-Wan, including a visible image with a clear eye and an infrared image showing cold high thunderstorm cloud temperatures. The typhoon has maximum sustained winds near 149 mph, generating extremely high waves.
The TRMM satellite captured heavy rainfall rates of up to 2 inches per hour in the center of the storm. Rainfall images are false-colored with yellow, green and red areas indicating rainfall between .78 to 1.57 inches per hour.
NASA's Aqua satellite revealed extremely high thunderstorms in Typhoon Choi-Wan as it approached the island of Sai-Pan. The typhoon is expected to bring heavy rainfall and strong winds to the area, with storm surge and inundation possible along shorelines.
Tropical Storm Koppu is expected to make landfall in mainland China on September 15, bringing heavy rainfall, heavy surf conditions, and gusty winds. The storm has sustained winds near 69 mph and is forecast to strengthen slightly before landfall.
The remnants of Typhoon Vamco are sweeping over Alaska's Aleutian Island chain, causing high wind warnings. The National Weather Service has posted warnings for gusts of 40-60 mph, with some areas reaching hurricane-strength winds.
Typhoon Vamco boasts an enormous 45-mile-wide eye with cold high thunderstorm cloud temperatures below minus 63 Fahrenheit. The storm is currently in the Northern West Pacific Ocean and will begin changing to an extra-tropical storm, moving into the North Central Pacific Ocean.
Typhoon Morakot brought catastrophic rainfall to Taiwan and China, with over 40 inches of rain recorded in central and northern Taiwan. The NASA TRMM satellite provided critical data on the storm's impact, allowing researchers to map areas of potential flooding and track its movement around the globe.
Typhoon Morakot's massive size and powerful winds have brought catastrophic effects to Taiwan, with reports of up to 20 inches of rain in mountainous areas. The storm's landfall is expected to occur on Saturday in mainland China, where it will then move north towards Shanghai.
NASA satellites observed Typhoon Morakot's rapid expansion from a 528-mile-wide storm to a massive 1,056-mile-diameter system. The typhoon's cold cloud tops indicate powerful thunderstorms and a significant threat to Taiwan and China.
Researchers found that typhoons trigger slow earthquakes in eastern Taiwan, with 11 events occurring within a five-year study period. The slow quakes are characterized by non-violent fault slippage events that release energy hours or days after the typhoon passes.
The Tropical Rainfall Measuring Mission satellite captured rainfall totals of over 900 mm in southern Luzon due to Tropical Storm Kujira and around 150 mm in northern Luzon from Typhoon Chan-hom. The TRMM-based Multi-satellite Precipitation Analysis system provides near-real-time data for monitoring global Tropics.
The University of Miami's Rosenstiel School of Marine, Atmospheric, and Earth Science has received a $3.75 million grant from the Office of Naval Research to support satellite-based research in the Western Pacific Ocean. The project aims to better understand typhoons, internal waves, and coastal processes using satellite data.
A recent Ohio State University study reveals that a single typhoon in Taiwan buries as much carbon in the ocean as all other rains combined, with 500,000 tons of carbon being washed away during Typhoon Mindulle. This finding could help scientists develop better models of global climate change.
The University of Miami's CSTARS will host a library of high-quality images collected via spaceborne C-Band Synthetic Aperture Radar (SAR) to aid in understanding hurricane and typhoon dynamics. The database will provide approved scientists with free access to imagery that can help shape storm models and resource distribution.
Engineers at MIT developed a simple system to determine an area's landslide risk using data on history of landslides, bedrock type, slope inclination, and vegetation growth. The tool is especially applicable to developing countries in Southeast Asia where detailed analysis has not been performed.
