Designs Would Put Surveillance Drones Over Hurricanes For A Week At A Time

The three designs above won a NASA competition to envision the next generation of hurricane surveillance drones. 

The agency asked teams to develop an unmanned aerial system (UAS) that could stay aloft for seven days at a time and offer persistent remote sensing over a period of five months. That timeframe covers a typical Atlantic hurricane season, and the agency’s goal is to closely follow storm formation from when a tropical wave moves off Africa’s west coast through the full life cycle of the weather system.

Current UASs used for tropical storm monitoring are similar to the military Global Hawk surveillance and security platform, and can only stay aloft for 24 hours at a time before they need to come home.

Powerful Model Could Help Predict Monsoons And Cyclones A Month Away

by Michael Keller

Japanese atmospheric scientists reveal they have cracked the code to model a complex weather phenomenon using a new supercomputer. They say their work will help build more accurate forecasts of monsoons and tropical cyclones up to a month away.

Their research focused on moving regions of wet and dry weather that travel over the warm parts of the Indian, Pacific and Atlantic oceans. These regions move eastward at up to 18 mph in a regular 30- to 60-day cycle of thunderstorms followed by suppressed precipitation. The phenomenon is called the Madden–Julian oscillation (MJO), and influences deadly monsoon and cyclone development. It has also been linked to the periodic El Niño/La Niña weather event in the eastern Pacific Ocean.

Efforts to model the globe-spanning MJO’s variability have been limited by the complicated physics that happens within the churning clouds. But atmospheric researchers at the Japanese Agency for Marine-Earth Science and Technology and the University of Tokyo employed the K computer to accurately recreate MJOs of the past, proving that it will be important for future forecasts.

by Michael Keller

There are a number of references that might come to mind when looking at these gifs: Starry Night, a shaken snow globe, the atmosphere of another planet or, perhaps for those of a certain age, Biz Markie’s Vapors.

While these are all fine images to conjure up, the animations here all come from a film made around 1947 to show how scientists make snow in a lab. It was part of research called Project Cirrus that was undertaken by GE and the U.S. government to see if people could weaken the destructive power of hurricanes. Though the project failed, weather researchers learned much about tropical cyclones.

Click on the gifs for a brief description or watch the full video posted by the Museum of Innovation and Science.

Tropical Cyclone Strength and Duration Spike This Year; Blocking Jams Sandy into East Coast

by Michael Keller

Though millions of people in the Western Hemisphere might have already had a suspicion that October was a busy month for tropical storms, the National Hurricane Center has put some official numbers on it.

The center says five tropical storms formed in October. Two developed into hurricanes, including Hurricane Sandy, which ravaged parts of New Jersey and New York. This puts the month’s activity well above the long-term average of two named storms and one hurricane.
