A radiosonde which is dropped by parachute from an aircraft for the purpose of obtaining soundings of the atmosphere below.

A radiosonde which is dropped by parachute from an aircraft for the purpose of obtaining atmospheric conditions. Hurricane hunters use dropsondes as they explore the strength and intensity of tropical cyclones. The sounding obtained is used for weather models to predict the future conditions of the tropical cyclone.

an expendable instrument package launched from the plane to return weather data as it falls

an instrument containing weather equipment that is dropped by the planes into the center of circulation to obtain surface conditions

a parachute-born weather sensing canister which, as it falls to the surface of the ocean, radios back to the weather aircraft the temperature, humidity, pressure and winds inside the storm

a small, round tube that is dropped into the eye of the hurricane

a specialized meteorological word for a weather balloon radiosonde that is dropped by parachute, usually from a plane, but sometimes lofted by a balloon

A modified radiosonde package that is dropped by parachute from an aircraft to obtain temperature, pressure, and humidity profiles of the atmosphere below flight level; often used by aircraft weather reconnaissance of hurricanes.

(Also called parachute radiosonde.) A radiosonde with a parachute dropped from an airplane carrying receiving equipment for the purpose of obtaining an upper-air sounding during descent.

A radiosonde dropped with a parachute from an aircraft rather than lifted by a balloon to measure the atmosphere below.
