Paper on the Coyote unmanned aircraft system in Hurricane Edouard released online in Earth and Space Science

This was the first successful launch of an unmanned aircraft system into a mature hurricane from a Hurricane Hunter aircraft. This so-called Coyote is a 13-pound drone with a 5-foot wingspan that measures pressure, temperature, humidity, and wind speed and direction.

 

Important Conclusions:

  • Data from the Coyote compared very well with other observations from Hurricane Hunter Aircraft.
  • The Coyote can fly in regions that are otherwise difficult to observe, especially near the warm ocean surface where heat, moisture, and energy fuel the hurricane.

One last flight into Karl

The P3 and G-IV are at it again for one last flight into Karl. The G-IV will take off at 1:30PM Eastern (1730 UTC) and the P3 will follow with a 2PM (1800 UTC) take off from St. Croix. Below are the proposed flight tracks. The dots on the flight tracks (shown in green) represent the aircraft turn points. The red dots in the figure show the locations that launch weather balloons twice a day while the purple dots are the locations that launch balloons once a day.

Another flight into Karl early this morning

We are still tracking Karl. It’s a stretch to fly from St. Croix but we can still gather data inside Karl. NOAA43 will take of at 2AM Eastern (0600 UTC) for an eight hour mission. Below is the proposed flight track. The dots on the flight track (shown in green) represent the aircraft turn points. The red dots in the figure show the locations that launch weather balloons twice a day while the purple dots are the locations that launch balloons once a day.

NOAA flight crews are ready to fly into Karl this afternoon

The G-IV jet and the P3 aircraft are gearing up to fly and collect data in and around Karl. These flights provide us with insight to the evolution of Karl. The various instruments onboard the aircraft measure different atmospheric parameters that together give us a better picture of Karl. The G-IV will take off at 1:30PM (1730 UTC) followed by NOAA43 taking off at 2:00PM (1800 UTC). Below are the proposed flight tracks. The dots on the flight track (shown in green) represent the aircraft turn points. The red dots in the figure show the locations that launch weather balloons twice a day while the purple dots are the locations that launch balloons once a day.

The P3 aircraft is on its way to fly into Karl

NOAA43 took off around 2AM this morning to fly into Karl. The P3 continues to gather weather data in Karl. The data collected is used by the forecasters at the National Hurricane Center. It also goes into the computer weather models to better predict the track and intensity of Karl. The P3 flies missions back to back to gather data continuously. Below is the proposed flight tracks. The dots on the flight track (shown in green) represent the aircraft turn points. The red dots in the figure show the locations that launch weather balloons twice a day while the purple dots are the locations that launch balloons once a day.

NOAA’s aircraft continue to gather data in Karl

NOAA’s G-VI jet and P3 will fly today to collect data in, around, and over Karl. The G-IV will take off first at 1:30PM (1730 UTC) followed by NOAA43 taking off at 2:00PM (1800 UTC). The objective for these two missions is to collect data and understand the atmospheric conditions around Karl and how the storm interacts with its surroundings. Below are the proposed flight tracks. The dots on the flight track (shown in green) represent the aircraft turn points. The red dots in the figure show the locations that launch weather balloons twice a day while the purple dots are the locations that launch balloons once a day.
