Paper on ice particles in tropical cyclones and how they are represented in forecast models published in Geophysical Research Letters

Summary:  In order to accurately forecast the weather, models must accurately represent how liquid water and ice particles in cloud form, grow, and disappear, how big and how many of each there are. To do that, we must know how this all works in real clouds.  The NOAA P3 Hurricane Hunter Aircraft have instruments called … Continue reading Paper on ice particles in tropical cyclones and how they are represented in forecast models published in Geophysical Research Letters

50th Anniversary of Hurricane Debbie seeding

Hurricane Debbie’s eye as seen from ESSA DC-6 On August 18th and 20th, 1969, Hurricane Debbie was subjected to a seeding experiment as part of Project STORMFURY.  STORMFURY was a joint Navy and Environmental Science Services Administration (ESSA, the predecessor of NOAA) project to test the hypothesis that seeding hurricanes with silver iodide would disrupt … Continue reading 50th Anniversary of Hurricane Debbie seeding

70th Anniversary of the first hurricane seeding experiment

On the afternoon of October 13, 1947, an Air Force B-17 aircraft penetrated a hurricane 415 miles (667 km) east of Jacksonville and dumped several pounds of crushed dry ice into the storm, just to see what would happen.  This was the first attempt to modify a tropical cyclone by seeding it with freezing nuclei.  … Continue reading 70th Anniversary of the first hurricane seeding experiment

40th anniversary of Hurricane Anita

On 16 August, 1977, a tropical wave moved off the coast of Africa.  It wasn't until nearly two weeks later that the wave developed enough convection and a surface circulation, and was designated a tropical depression in the middle of the Gulf of Mexico.  The system slowly moved west-southwestward, but rapidly intensifying into a category-5 … Continue reading 40th anniversary of Hurricane Anita

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 … Continue reading 25th Anniversary of Hurricane Andrew striking South Florida

Paper on the types and sizes of ice particles in hurricanes published in the Journal of Applied Meteorology and Climatology

Many people have experienced the heavy rain and warm, moist air when hurricanes reach land. But several miles above the ground, where the air is very cold, hurricane clouds are made up of snowflakes and tiny ice particles called ice crystals. The computers that scientists use to forecast where hurricanes will go and how strong … Continue reading Paper on the types and sizes of ice particles in hurricanes published in the Journal of Applied Meteorology and Climatology
