Satellite system to change how meteorologists predict hurricanes

Last Updated by Martha Jasso on

SciTech Now gets a first look at the Cyclone Global Navigation Satellite System (CYGNSS) Hurricane Mission. The collaboration between Southwest Research Institute, NASA and the University of Michigan has resulted in a creation of eight microsatellites that will gather never-before-seen details on the formation and intensity of tropical cyclones and hurricanes. Follow along as SciTech Now learns about how CYGNSS will change the way meteorologists predict and forecast hurricanes.

Hurricanes can cause serious damage to many communities, fatally, structurally and financially. Meteorologists are currently only able to forecast the traveling direction of a storm, but have yet to measure the internal force building within the core. Not having adequate equipment able to read through heavy precipitation has resulted in very little improvement in the accuracy of hurricane intensity forecasts.

CYGNSS will be the first satellite able to collect surface wind data combined with precipitation fields. It will also be the first to measure surface winds in and near the inner core of hurricanes, including regions beneath the eyewall and intense inner rain-bands that will allow weather broadcasters to improve forecasts. This information is vital to emergency managers in charge of safety protocol.  For the general public to know information ahead of time will be helpful in providing adequate warning of approaching storms, give the community time to get to a safe, secure place, and have resources readily available to them.
