Paper on a way to initialize idealized hurricane models released online in the Journal of Advances in Modeling Earth Systems

Computer models developed to forecast the weather need to know what is currently happening in the atmosphere and in the ocean, what we call “initial conditions,” each time the model starts. The process of making these initial conditions is known as “initialization.” This study is about a new initialization method for both the atmosphere and …

10th Anniversary of Aerosonde flying into hurricane-force winds

On November 2, 2007, an unmanned aerial vehicle (UAV) Aerosonde flew into Tropical Storm Noel.  This marks the first time a UAV flew into an Atlantic tropical cyclone while encountering hurricane-force winds. The flying probe was produced by the Australian-based Aerosonde Pty Ltd. (now Textron Systems) which had been manufacturing sensors since 1995.  It reached …

The unmanned aerial system, Coyote gathers data in Hurricane Maria

On September 22-23, scientists with AOML's Hurricane Research Division collected unique data from six Coyote UAS (unmanned aircraft system) launched from NOAA’s P3 Hurricane Hunter aircraft into Hurricane Maria. The Coyote UAS gathered atmospheric, temperature, pressure, and moisture data in Maria’s eye and eyewall at altitudes as low as 300 feet above the ocean surface. The …

25th Anniversary of Hurricane Andrew striking South Florida

In the early morning hours of August 24, 1992, Category-Five Hurricane Andrew roared across southern Florida leaving behind a trail of devastation that stunned the nation.  Andrew was the first hurricane of this ferocity to hit the continental United States since Hurricane Camille in 1969, and repercussions of its landfall were felt in the world …
