Latest Tropical cyclone Stories
Cutting-edge NASA technology has made this year's NASA Hurricane mission a reality. NASA and other scientists are currently flying a suite of state-of-the-art, autonomously operated instruments that are gathering difficult-to-obtain measurements of wind speeds, precipitation, and cloud structures in and around tropical storms. "Making these measurements possible is the platform on which the instruments are flying," said Paul Newman, the deputy principal investigator of NASA's Hurricane and...
NASA's Aqua satellite revealed a large area of powerful thunderstorms around the center of Tropical Storm Miriam on Sept. 23 as it tracked through the Eastern Pacific Ocean. That power was the trigger that helped Miriam rapidly intensify into a major hurricane on Sept. 24. NASA's Aqua satellite passed over the eastern Pacific Ocean on Sept. 23 and the Atmospheric Infrared Sounder (AIRS) instrument captured an infrared image of Tropical Storm Miriam's cloud top temperatures. Tropical Storm...
redOrbit Meteorologist Joshua Kelly Big Story Weather from September 24: Another cold evening occurred this time from the Midwest eastward into the Northeast as the area of high pressure continued to make its way eastward. There was no major severe weather from yesterday as most of the nation was dry or cold. The only place that did see rain showers was South Florida along the stationary boundary. Weather Outlook for September 25: High pressure will shift off the East Coast...
The tropical cyclones in the Arabian Sea during the pre-monsoon season (May – June) have intensified since 1997 compared to 1979 - 1997. This has been attributed to decreased vertical wind shear due to the dimming effects of increased anthropogenic black carbon and sulfate emissions in the region. The decrease in vertical wind shear, however, is not the result of these emissions, but due to a 15-day on average earlier occurrence of tropical cyclones, according to a study spearheaded by Bin...
redOrbit Meteorologist Joshua Kelly Big Story Weather from September 21-23: The cold air of old man winter arrived in places like North Dakota, South Dakota, Minnesota and Iowa. Many of these places enjoyed the cold record setting air over the weekend as temps dropped into the 20’s. Also the Northern part of Minnesota got a tease of snow with upwards to 1 inch. The west dealt with the heat as many places in California had temps soar into the 90’s and even 100’s. On Friday an...
NOAA's GOES satellite captured Tropical Storm Nadine in the eastern Atlantic, another low pressure area forming in the central Atlantic, and a developing low in the eastern Pacific. NASA's TRMM satellite noticed that the storms around Nadine's center were waning. On Sept. 21 at 7:45 a.m. EDT, NOAA's GOES-13 satellite captured an image of Tropical Storm Nadine in the eastern Atlantic, and a developing low in the central Atlantic. Nadine is south of the frontal boundary draped across the...
Scientists and forecasters have been analyzing Tropical Storm Nadine using various NASA satellites as NASA's Global Hawk flew over the storm gathering information. Both the Global Hawk and NASA's TRMM satellite noticed that Nadine has continued to display tropical characteristics, indicating that it has not transitioned to an extra-tropical storm. Forecasters noted that Nadine could have started transitioning into an extra-tropical storm, because there was little significant rainfall near...
redOrbit Meteorologist Joshua Kelly Big Story Weather from September 19: A weak frontal boundary moved through the Great Lakes and brought some precipitation to places like Chicago and around Lake Michigan. The big story was the cold air that took hold over the Plains and also parts of the Northeast. The warm air continued over the western part of the United States. Severe weather was limited to WI with hail and wind reports the main threat. Weather Outlook for September 20: A cold...
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...
SAN DIEGO, Sept. 19, 2012 /PRNewswire/ -- EarthRisk Technologies, a pioneer in the research, analysis and visualization of extreme temperature and weather pattern risks, is expanding their meteorological research into the realm of hurricanes. EarthRisk's science team, in collaboration with academic researchers such as Josh Cossuth, a PhD student at the Florida State University Center for Atmospheric Prediction Studies , is working on quantifying past hurricane errors in order to...

Tropical Storm Alberto was named the first tropical storm of the Atlantic 2012 Hurricane Season on May 20th at 1200PM CDT. The location of the storm at this time was just to the southeast of South Carolina. The winds were estimated at 40kts gusting to 50kts. On May 20th at 0600PM CDT Tropical Storm Alberto had winds estimated at 45kts with gust to near 55kts. At this time the storm was just to the east of Savannah Georgia and was moving towards the southwest. May 21st at 0600PM CDT...
Say it’s not so, but we could be very well on the verge of entering into an EL-Nino cycle soon. How soon? The latest forecast issued by the Climate Prediction Center has upped the chances of seeing EL-Nino this year now at 61% with the favorable time period pointing towards the 3rd quarter (July-September). What does this mean to you? Well it all depends on where you’re living as EL-Nino has a wide array of impacts that are different everywhere around the globe. Here are a few...
Coastal Upwelling- this is defined as the moving of water from the deeper oceans upwards to the surface of the ocean very commonly found along our cold ocean currents, which are found along the West Coast of the United States and off the Peru coast. Coastal Sinking- this is defined as the warm waters moving in from the east and hitting the coastline and slowly filtering down towards the deeper ocean waters very slowly. This feature is common in our warm ocean currents such as the United...
Tropical Storm Debbie on a surface chart. It is noted that just off the coast of Northern Florida a 999 surface pressure is found indicating to a meteorologist that an area of Lower pressure is arriving. In this case it’s Tropical Storm Debbie. The red lines indicate lines of equal pressure. Meteorologists label them in 4mb increments. So looking at the map it’s noted that there is a 08/04/00/96 line present in the photo highlighted with red. Another feature is that the more of these...
Onshore flow describes the movement of any weather feature moving towards the shore. The most common weather features that are affiliated with onshore flow are Hurricanes and the daily sea breeze. What happens with a hurricane is the Northeast side of the storm will produce winds out of the Southeast to South which will force the ocean water (Storm Surge) towards the coast along with all the extensive precipitation shields. Another feature is known as the Sea breeze. The sea breeze happens...
