A Hurricane Hunters engineer captured video from inside Hurricane Helene's eye Wednesday after it formed along the Gulf of Mexico.
Annular hurricanes have been simulated that have gone through the life cycle of an eyewall replacement. The simulations show that the major rainbands will grow such that the arms will overlap, and then it spirals into itself to form a concentric eyewall. The inner eyewall dissipates, leaving a hurricane with a singular large eye with no rainbands.
A Saildrone sent into the heart of Hurricane Sam is offering scientists the first views of conditions at the water's surface from inside a major hurricane. Drone video shows Category 4 Hurricane ...
The F09 storm with the K microphysics parameterization had the largest eye and the strongest winds at large radii, while the L storm was most intense and WSM3 had the most compact eye. F09 noted that storm with stronger outer winds tracked more to the northwest than storms with weak winds.
The Hurricane Surge Index is a metric of the potential damage a storm may inflict via storm surge. It is calculated by squaring the dividend of the storm's wind speed and a climatological value (33 m/s or 74 mph), and then multiplying that quantity by the dividend of the radius of hurricane-force winds and its climatological value (96.6 km or ...
One of the newest and tiniest tools, is a StreamSonde: A small cylinder seems right out of a climactic scene in the movie "Twister."
This project set out to seed clouds outside the eyewall, causing a new eyewall to form and weakening the storm. When it was discovered that this was a natural process due to hurricane dynamics, the project was quickly abandoned. [8] Research shows that 53 percent of intense hurricanes undergo at least one of these cycles during its existence. [15]
To form, hurricanes need waters of at least 80 degrees Fahrenheit. Warm water rises into the air, and as it rises, it creates lower air pressure beneath it. Nearby air rushes in, and the process ...
