Observational tools

Before we can predict what a storm will do in the future, we need to know what the storm, the atmosphere, and the ocean look like right now!

Radiosondes: Instruments attached to weather balloons that transmit temperature, humidity, & wind data back to the ground. These balloons are launched globally twice a day.

Aircraft:Commercial aircraft regularly report weather data. NOAA “Hurricane Hunter” aircraft penetrate hurricanes to gather valuable data on the storm.

Satellites:Gather data on clouds, water vapor, and land & sea surface temperatures.

Observational Tools

Surface:Thousands of weather stations across the globe report weather conditions every hour.
