Philippine's Tropical Cyclone Rainfall 2013

In a normal year 30% of the total rainfall near the Philippines (northwestern Pacific Ocean) is caused by tropical cyclones. The most notable tropical cyclone this year was deadly super typhoon HAIYAN that devastated the central Philippines in November 2013. The TRMM-based, near-real time Multi-satellite Precipitation Analysis (TMPA) at the NASA Goddard Space Flight Center was used to analyze only rainfall near tropical cyclones passing close to or over the the Philippines in 2013. The TMPA analysis above shows the estimated total rainfall contributed by named tropical cyclones this year. Red

GPM Undergoes Post-Shipment Inspections

Following arrival in a cleanroom at the Tanegashima Space Center in Japan, the Global Precipitation Measurement (GPM) core observatory was attached to a custom-designed satellite mount which allowed the NASA team on-site to perform preliminary inspections and evaluations of the spacecraft.

When asked to picture the shape of raindrops, many of us will imagine water looking like tears that fall from our eyes, or the stretched out drip from a leaky faucet. This popular misconception is often reinforced in weather imagery associated with predictions and forecasts.

Raindrops are actually shaped like the top of a hamburger bun, round on the top and flat on the bottom. This new video from the Global Precipitation Measurement mission explains why.

Tropical Cyclone Alessia Soaks Northern Australia

During the past weekend tropical cyclone ALESSIA weakened to a tropical low as it moved from the Timor Sea over Northern Australia. The warm waters of the Gulf Of Capentaria have helped revive ALESSIA to tropical storm intensity today. The image on the right shows TRMM satellite data collected on November 27, 2013 at 0225 UTC. A 3-D perspective view (from the west) shows the tropical cyclone's vertical structure based on radar reflectivity data collected by TRMM's Precipitation Radar (PR) instrument. Thunderstorm towers are shown reaching heights above 16km (~9.92 miles) in a feeder band east

GPM Arrives at Tanegashima Space Center

Following arrival at Japan’s Kitakyushu Airport at 10:30 p.m. EST Saturday, Nov. 23, the GPM Core Observatory spacecraft in its shipping container was off-loaded from the C-5 aircraft and moved to a barge to be transported to Tanegashima Island. GPM's shipping container is unloaded from the U.S. Air Force C-5 cargo plane that carried it to Japan.

The barge arrived at
