Tracking California Rains During El Niño

1.03K Views0 Comments

This winter, areas across the globe experienced a shift in rain patterns due to the natural weather phenomenon known as El Niño. New NASA visualizations of rainfall data show the various changes to California. According to the National Oceanic and Atmospheric Administration, El Niño was expected to produce wetter-than-average conditions from December 2015 to February 2016. Scientists refer to historical weather patterns and to look at trends of where precipitation normally occurs during El Niño events. Also, several factors—not just El Niño—can contribute to unusual weather pattern.

Hurricane Forecasts Rely on Modeling the Past

Improving hurricane forecasts means testing historical storms with today's sophisticated models and supercomputers. NASA and NOAA work together in gathering ground and satellite observations, as well as experimenting with research forecast models. As a result of this collaboration, model resolution has increased, and scientists are discovering more about the processes that occur within these powerful storms. The Global Precipitation Measurement (GPM) Mission is a joint NASA and Japan Aerospace Exploration Agency (JAXA) mission that measures all forms of precipitation around the globe. GPMs Microwave Imager, or GMI, has proven useful in seeing beneath the swirling clouds and into the structure of tropical cyclones. The information gathered by GPM and other missions will be used to improve forecast models.
