20th anniversary of the first ever dropwindsonde observation in a hurricane eyewall

For decades, meteorologists used dropwindsondes, weather instrument packages deployed from aircraft, to make atmospheric soundings below flight level.  Starting in the 1970s they used Omega dropwindsondes (ODWs) that employed the very low-frequency Omega navigation signals to estimate the ODW’s motion relative to the aircraft, and subsequently calculate the wind.  Because of the limitations of this system, […]

25th Anniversary of Project TEXMEX

Starting in July 1991 and running through August, MIT and NOAA carried out the Tropical Experiment in Mexico (TEXMEX).  The purpose of the project was to examine the thermal and humidity structure of the near surface layer of the atmosphere in the tropical eastern Pacific and attempt to relate elevated levels of high theta-e (equivalent […]
