Known affectionately as the "Hurricane Hunters," the Lockheed WP-3D Orion is the workhorse of the NOAA fleet. These turboprop aircraft, originally designed for maritime patrol, have been heavily modified for hurricane reconnaissance. They're built like tanks, able to endure the turbulence and high winds that come with flying through a hurricane. The P-3 Orions are easily recognizable by their distinctive bulges and antennae, which house an array of scientific instruments.

Inside the P-3 Orion, you'll find a team of scientists and flight crew working tirelessly to collect data. The aircraft is equipped with sophisticated instruments, including:

  • Doppler Radar: This radar system provides detailed information about the storm's structure, wind speeds, and rainfall intensity. It's like having an X-ray vision for hurricanes!
  • Airborne Expendable Bathythermograph (AXBT): These instruments are dropped into the ocean to measure water temperature. This data helps meteorologists understand the energy available to fuel the hurricane.
  • GPS Dropwindsondes: These instruments are released from the aircraft and descend through the storm, measuring wind speed, direction, temperature, and humidity. They provide a crucial vertical profile of the hurricane's atmosphere.

The P-3 Orions fly directly through the eye of the hurricane multiple times, collecting data that is used to improve the accuracy of hurricane forecasts. They are truly the eyes and ears of NOAA's hurricane forecasting efforts.

Gulfstream IV-SP (G-IV)

While the P-3 Orions get the job done by going straight into the eye of the storm, the Gulfstream IV-SP (G-IV) provides crucial data from a higher altitude and wider range. This is a business jet, and it is a jet aircraft, which makes it faster than the P-3 Orions. The G-IV plays a vital role in hurricane reconnaissance.

The G-IV's primary mission is to collect data about the environment surrounding the hurricane. It does this by flying at altitudes up to 45,000 feet, which provides a broader perspective of the storm's overall structure and the conditions that might influence its path. The G-IV is equipped with a variety of instruments, including:

  • Stepped Frequency Microwave Radiometer (SFMR): This instrument measures the ocean's surface wind speed and rainfall rates. It's especially useful for assessing the intensity of a hurricane over the ocean.
  • GPS Dropwindsondes: Like the P-3 Orions, the G-IV also deploys these instruments to collect data on wind speed, direction, temperature, and humidity, providing essential information about the hurricane's vertical structure.
  • Airborne Doppler Radar: Similar to the P-3's radar, this system provides valuable data on the storm's internal structure and wind patterns.

The G-IV's high-altitude observations are incredibly valuable for improving the accuracy of hurricane models and forecasts. It is used in order to obtain a big picture of the storm. The aircraft is used to assess the intensity of the hurricane, but it focuses on surrounding parameters such as wind speed.
