During each pass through the eye, they release a dropsonde, which collects weather data on its descent to the ocean surface, specifically gathering data on the surface winds and pressure.
The morning dropsonde launched over the ocean close to Henties Bay (0951 UTC) revealed the presence of a sharp relative humidity transition from 80% to less than 5% at the top of the BBA layer at close to 6 km MSL (Fig.
For intensification and weakening, we rely mainly on dropsonde measurements and infrared satellite imagery.
During each pass through the center, they release a dropsonde, which collects weather data on its descent to the ocean surface, specifically gathering information about the surface winds and pressure.
The aircraft is equipped with 25 instruments of advanced weather reconnaissance equipment, including a dropsonde, an expendable weather reconnaissance device, a radioactivity detector, and a data acquisition system.
He waits for the weather officer to give him the signal to drop the first biodegradable dropsonde that will collect the vital data on the storm as it falls attached to a parachute to the ocean surface.
Drops in the ocean In order to measure hurricane wind speeds using the standard method, scientists drop a 16-inch-long tube packed with scientific instruments called a dropsonde. These dropsondes are attached to small parachutes and jettisoned from airplanes, gathering information during their descent.
As the aircraft enters the eye wall, the Airborne Weather Reconnaissance Officer (AWRO) releases a dropsonde, a weather instrument that determines the maximum surface winds of the storm.
NOAA GOES satellite, NDBC Buoy and NHC dropsonde data for sea surface temperature and meteorological variables including air temperature, wind speed and sea level pressure were used for computations.
The CMO's Chemical Detection Remote Sensing System program is investigating dropsonde chemical detectors, ultraspectral sensors that can analyze gas particles for distinctive signatures (e.g., nerve gas), then transmit an alert to nearby soldiers on a chemical/biological warning net.
The remote sensing systems are complemented by a dropsonde capability, whereby HALO is equipped to launch Vaisala RD-94 sondes using an "Airborne Vertical Atmospheric Profiling System" (Hock and Franklin 1999).
