As Hurricane Melissa approached Jamaica last month, a NOAA Hurricane Hunter airplane dropped a fleet of weather instruments called dropsondes into the depths of the storm. When the National Hurricane Center received the dropsonde data from the plane via satellite and processed the 252 mph reading, they cautiously began referring to the measurement as a potential record. In order to verify the reading, they contacted researchers at the U.S. National Science Foundation National Center for Atmospheric Research (NSF NCAR), where dropsondes were developed, and asked them to verify the data.  

Scientists are experimenting with high-resolution global forecasts to improve predictions of hurricanes and extreme rainfall.

The In-situ Collaborative Experiment for the Collection of Hail In the Plains (ICECHIP) field campaign was the first major U.S. hail field campaign in over 40 years. Over 10,000 hailstones were collected, a selection of which are now being analyzed at the U.S. National Science Foundation National Center for Atmospheric Research (NSF NCAR). 

A prototype turbulence detection system is designed to guide aircraft worldwide from areas of rough air.

An expert in polarimetric, dual-wavelength, and phased array radar technologies, Vivekanandan has collaborated extensively with Indian scientists to advance understanding of monsoon precipitation.
