Warming Cloud Tops Indicating Tropical Storm Tony Weakening Seen By NASA
2012-10-26 08:24:20

In a tropical cyclone, strong uplift of air pushes the tops of thunderstorms high into the troposphere. When that strength wanes, the cloud tops drop and become less cold. That's because the higher you go in the troposphere, the colder it gets. NASA satellite infrared data has revealed that Tropical Storm Tony's cloud top temperatures are warming and the storm is weakening. The Atmospheric Infrared Sounder (AIRS) instrument aboard NASA's Aqua satellite captured infrared imagery of Tropical...

Stubborn Nadine Intensifies Into A Hurricane Again Seen By NASA
2012-09-28 13:32:44

Infrared data from NASA's Aqua satellite today, Sept. 28, revealed strong convection and thunderstorms have built up again in Tropical Storm Nadine as it moved over warm waters in the Eastern Atlantic Ocean. That convection strengthened Nadine back into a hurricane today. Nadine has lasted over two weeks, but is nowhere near breaking the record for longest-lived tropical cyclone. NASA's Aqua satellite passed over long-lived Nadine on Sept. 28 at 0441 UTC (12:41 a.m. EDT) when it was still...

Post-Tropical Cyclone Lane Fizzles In A Blanket Of Low Clouds Seen By NASA
2012-09-19 12:55:21

Former Hurricane Lane has fizzled and its remnant circulation was spotted in a blanket of low clouds in the Eastern Pacific Ocean. NOAA's GOES-15 satellite sits in a fixed orbit over the western U.S. and captures continuous visible and infrared imagery of the western U.S. and the Eastern Pacific Ocean. On Sept. 19 at 11:45 a.m. EDT, GOES-15 captured a visible image of post-tropical Lane's remnants that appear as a small circulation center. The center was located over 1,000 miles from Baja...

Short Life Of Tropical Depression John Seen By NASA

Tropical Storm John had about one day of fame in the Eastern Pacific. Born Tropical Depression 10, it intensified into Tropical Storm John on Sept. 2 at 5 a.m. EDT and maintained maximum sustained winds of 40 mph (65 kmh) until it weakened back into a depression on Monday, Sept. 3 at 11 p.m. EDT. NASA's Aqua satellite flew over John on Sept. 3 at 2041 UTC (4:41 p.m. EDT) during its brief time as a tropical storm and noticed convection (rising air that forms thunderstorms that make up the...

Infrared imagery provides forecasters with a look at the temperature of cloud tops in tropical cyclones, sea surface and land surface temperatures and more. NASA infrared imagery from the morning of June 24 revealed that Darby had strong convection that is an indicator of a strengthening storm. Tropical Storm Darby became the second hurricane of the Eastern Pacific Ocean season this morning. When NASA's Aqua satellite flew over Darby on June 24 at 08:23 UTC (4:23 a.m. EDT), the Atmospheric...

Tropical Storm Josephine intensified overnight over the central Atlantic Ocean, forecasters at the U.S. National Hurricane Center in Miami said Thursday. The 10th named storm of the Atlantic storm season was about 465 miles west of the southernmost Cape Verde Islands at 5 a.m., with sustained winds near 60 mph, the forecasters said. Josephine's winds extended 105 miles from the storm center. The system was moving west-northwest near 10 mph and that motion was forecast to continue for two...
