Ask The Weatherman for August 28, 2013:
Question: What do hurricane hunters use to gather weather data inside a storm?
Answer: They use a radio-sonde that is dropped from an airplane and it sinks from the upper levels to the surface. This sonde gathers data such as wind speeds, wind direction, air temperatures, and pressure. All of this data is then used to help plot a storm and what is going on within the storm such as which direction it might be moving and if it’s getting stronger or weaker. This data is then transferred to the National Hurricane Center in Miami Florida to issue warnings.
