GPM Satellite Examines Tornadic Thunderstorms

Over the past few days tornado spawning thunderstorms have occurred in the states of Texas, Oklahoma, Arkansas, Louisiana, Indiana, Mississippi, Alabama and Georgia.

The size of falling raindrops depends on several factors, including where the cloud producing the drops is located on the globe and where the drops originate in the cloud. For the first time, scientists have three-dimensional snapshots of raindrops and snowflakes around the world from space, thanks to the joint NASA and Japan Aerospace Exploration Agency Global Precipitation Measurement (GPM) mission.
