Hurricane on Saturn

NASA Cassini spacecraft captured big hurricane on Saturn

The big hurricane on a surface of Saturn, similar to a rose bud, captured the NASA Cassini spacecraft. Scales of the hurricane impress: its diameter makes 2 thousand km that in 20 times more, than the biggest hurricane on Earth. Cassini allowed researchers to make out for the first time a hurricane on Saturn in detail. Wind speed in the hurricane center as it became clear, reaches 150 m/second. Unlike terrestrial storm, which move on a planet, the hurricane on Saturn isn’t mobile and is on its North Pole. On Earth hurricanes, as a rule, drift to the north, because of the turbulences of a wind caused by movement of a planet.

Cyclone Ethel

NASA Reveals Cyclone Ethel Power

NASA’s Aqua satellite saw icy cold cloud top temperatures in Tropical Storm Ethel on January 19, which hinted at intensification. Infrared satellite imagery gives forecasters a clue to how high the cloud tops are that belong to thunderstorms that make up a tropical cyclone. The rule is the higher the cloud top, the stronger the uplift and the stronger the thunderstorm. When NASA’s Aqua satellite passed over Ethel on January 19 at 09:17 UTC (4:17 a.m. EST) the Atmospheric Infrared Sounder (AIRS) instrument measured the temperatures of Ethel’s cloud tops. Thunderstorm cloud tops around the entire center of circulation and in some of the bands of thunderstorms that circled the center to the east and north, were colder than -63 Fahrenheit (-52 Celsius).
