Deadly Flooding and Landslides With Tropical Storm Jangmi

Jangmi became the 23rd named tropical cyclone in the western Pacific Ocean when it formed southeast of the Philippines on December 28, 2014. Heavy rainfall from Tropical storm Jangmi recently produced flooding and landslides in the Philippines that have reportedly killed over 30 people. The Philippines frequently gets hit by tropical cyclones. Tropical storm Jangmi hit only three weeks after slow moving typhoon Hagiput churned through the central Philippines. The TRMM satellite had a fairly good view of Jangmi on December 29, 2014 at 1425 UTC. The TRMM Microwave Imager(TMI) instrument showed

California's Drought Improving

Waves of rainfall from Pacific Ocean storms show signs of improving the exceptional drought conditions that have been plaguing California. Starting on about November 30, 2014 storms frequently moved over California. A Multi-satellite Precipitation Analysis (MPA) using data (3B42) archived at near "real time" at the NASA Goddard Space Flight Center was used in the analysis. It indicates that northern California has had far more beneficial rainfall than southern California. This analysis shows that storms dropped over 350mm (almost 14 inches) in an area north of San Francisco. Southern
Document Description

This document provides a basic set of documentation for the data products available from the GPM Ground Validation System (GVS) Validation Network (VN). In the GPM era the VN performs a direct match-up of GPM’s space-based Dual-frequency Precipitation Radar (DPR) data with ground radar data from the U.S. network of NOAA Weather Surveillance Radar-1988 Doppler (WSR-88D, or “NEXRAD”). Ground radar networks from international partners are also part of the VN.

"Pineapple Express" Brings Heavy Rains, Flooding to U.S. West Coast

The West Coast, which has been suffering from a strong drought, is finally seeing some much needed relief as a steady stream of storms and rain pour into the coast from the Pacific. The rains began in Washington and Oregon and have now worked their way down the coast to southern California. The weather pattern responsible for all of the rain is known as the "Pineapple Express." The Pineapple Express is known as an atmospheric river. A large, slow-moving low pressure center off of the West Coast taps into tropical moisture originating around the Hawaiian Islands, which is then channeled
