Oklahoma Mesoscale Convective System (MCS) Examined With GPM

The GPM Core observatory satellite's passed over Oklahoma on Monday, June 25, 2018 04:08 AM CDT (0508 UTC). The satellite makes measurements of precipitation with it's GPM's Microwave Imager (GMI) and Dual-Frequency Precipitation Radar (DPR) instruments every 95 minutes as it orbits the earth at 252.3 miles (407 km). The area covered by GPM's radar is shown in lighter shades.

Storm Structure and Mesoscale Dynamics

Seeing Through the Clouds

Satellites allow us to observe changes in the precipitation structure over the life cycle of a storm, even over ocean and regions where conventional data are sparse. In particular, we now have insights into the dynamics of a storm, such as how the eye of a hurricane stays stable as the storm moves across the Earth’s surface, and how tropical cyclones intensify through the presence of “hot tower” structures.
