This has been an active tropical cyclone season in the South Indian Ocean. The TRMM satellite passed over another forming tropical cyclone (15s) in the South Indian Ocean on 2 March 2012 at 0140 UTC. A rainfall analysis from TRMM's Microwave Imager (TMI) and Precipitation Radar (PR) instruments is shown on the image above. This "top down" view shows that very heavy rainfall of over 50mm/hr (~2 inches) was occurring near the center of the storm's circulation. TRMM's Precipitation Radar (PR) was used in the image above to show the 3-D structure of the forming tropical cyclone. Powerful storm

They captured a wide array of different types of snow and rain from Eastern New York as the DC-8 flew in from Maine to north of the CARE site in Huronia and Georgian Bay, off of Lake Huron
