How do we know about clouds?
Studying clouds from the air

hh Sometimes the best way to study a cloud is to get into the middle of it. We can do this with radiosondes, which gather data as they rise into the air, and with airplanes. Even though such airplane flights can be dangerous and unpredictable, sometimes they are the only way to collect crucial data.

For example, U.S. Air Force and NOAA pilots fly through hurricanes to collect data that is critical in determining their threat and cannot be obtained from satellite.

The planes carry between six to fifteen people. The flight crews consist of a pilot, co-pilot, flight engineer, navigator, and electrical technicians. The weather crew might consist of a flight meteorologist, lead project scientist, cloud physicist, radar specialist, and dropsonde operators. A dropsonde is like a radiosonde, except it is dropped from a plane and gathers data from the top down, rather than from the bottom up.

The primary purpose of reconnaissance is to track the center of the hurricane's circulation and to measure the maximum winds. The crews are also evaluating the storm's size, structure, and development.
