Tropical Storm Emily Weakens but May Revive

Tropical Storm Emily dissipated after being disrupted by the mountains of Hispaniola but according to the National Hurricane Center (NHC), may revive again within a couple days while moving toward the northwest. The TRMM rainfall analysis on the right, from a TRMM orbit on 4 August 2011 at 0934 UTC ( 5:34 AM EDT), shows that heavy rainfall was being produced by the dissipating storm over southern Haiti and the Dominican Republic at that time.

TRMM Sees Rainy Emily

The TRMM satellite saw tropical storm Emily again on 4 August 2011 at 0122 UTC (9:22 PM EDT). An analysis of TRMM's Microwave Imager (TMI) and Precipitation Radar (PR) data showed that Emily was dropping heavy rainfall of over 50mm/hr (~2 inches) south of the Dominican Republic and produce some showers in Haiti. Life threatening flooding and landslides are possible as Emily moves slowly westward.

Typhoon Muifa To Affect Okinawa

Typhoon Muifa had wind speeds of about 95 kts (~109 mph) when the TRMM satellite passed above on 3 August 2011 at 1307 UTC. Muifa is now predicted to pass just to the south of the Japanese Island of Okinawa. The southern tip of the Okinawa is expected to be in the right front quadrant of the typhoon on 5 August 2011 where the highest winds are normally located. TRMM's Microwave Imager (TMI) and Precipitation Radar (PR) data were used in the rainfall analysis shown on the right. See earlier TRMM information about typhoon Muifa.
Document Description

During the GPM pre-launch period physically-based snowfall retrieval algorithms are in an active phase of development. Further refinement and testing of these emerging algorithms requires the collection of targeted ground-validation datasets in snowing environments. This document describes a field campaign effort designed to provide both new datasets and physical insights related to the snowfall process- especially as they relate to the incorporation of appropriate physics into GPM snowfall retrieval algorithms.
