NASA Sees Ragged Eye Develop In Tropical Cyclone Guito
2014-02-20 09:41:29

Rob Gutro - NASA NASA satellite data was an "eye opener" when it came to Tropical Cyclone 15S, now known as Guito in the Mozambique Channel today, Feb. 19, 2014. NASA's Aqua satellite passed over Guito and visible imagery revealed a ragged eye had developed as the tropical cyclone intensified. The Moderate Resolution Imaging Spectroradiometer or MODIS instrument aboard NASA's Aqua satellite captured a visible image of Tropical Cyclone Guito on Feb. 19 at 1140 UTC/6:40 a.m. EST as it...

NASA Sees High Thunderstorms In Tropical Cyclone Fobane
2014-02-12 13:27:27

NASA/Goddard Space Flight Center Tropical Cyclone Fobane was located southeast of Reunion Island in the southwest Indian Ocean when the TRMM satellite passed over and captured rainfall and cloud data on the storm. TRMM saw that despite Fobane weakening, there was still some punch left in a few of the thunderstorms within. The Tropical Rainfall Measuring Mission or TRMM satellite passed over Fobane on February 11, 2014 at 0035 UTC. Fobane was very small but contained a few powerful...

Tropical Cyclone Edna Brushes By New Caledonia
2014-02-05 13:17:18

NASA NASA's Aqua satellite spotted two storms in one image in the Southern Pacific Ocean as Tropical Cyclone Edna brushes by New Caledonia and an extra-tropical storm lingers west of New Zealand. New Caledonia warnings were still in effect on February 5 as Edna continues moving along the southwestern part of the island. An Amber Alert was in effect for the whole southern province as well as the community of Canala and a Yellow Alert was in effect for the rest of the territory. NASA's...

NASA Sees System 91S Struggling
2014-01-31 14:20:56

NASA/Goddard Space Flight Center NASA's Aqua satellite provided infrared data on System 91S in the Mozambique Channel that showed a system battered by wind shear, stretched out, with broken convection. A false-colored infrared image was created at the Naval Research Laboratory in Washington, D.C. using infrared data from the MODIS instrument aboard NASA's Aqua satellite on January 31 at 11:05 UTC/6:05 a.m. EST. The MODIS image showed the strongest thunderstorms associated with System...

NASA Sees Tropical Cyclone Dylan Making Landfall In Australia
2014-01-30 16:05:31

NASA NASA's Aqua satellite passed over Tropical Cyclone Dylan and captured both visible and infrared imagery of the storm as it began landfalling. The visible image showed the extent of the storm, while the infrared data looked at the temperature of cloud tops to determine strong storms were already affecting the coast. The southwestern side of the storm had already started to make landfall in Queensland. Two instruments that fly aboard NASA's Aqua satellite were working to gather data...

Cyclone Watch Issued In Australia As NASA Sees System 99P Developing
2014-01-29 09:40:43

NASA NASA's Aqua satellite passed over the tropical low pressure area designated as System 99P and infrared data shows that the low is getting organized. Meanwhile, the Australian Bureau of Meteorology posted a Cyclone Watch for coastal areas from Port Douglas to Proserpine, Queensland that are expected to be affected by the storm. NASA's Aqua satellite passed over System 99P the Southern Pacific Ocean on January 28 at 14:47 UTC/9:47 a.m. EST and saw that some of the thunderstorms had...

NASA Sees Birth Of Tropical Cyclone Deliwe
2014-01-17 13:19:51

NASA The tropical depression southwest of Madagascar on January 16 developed into a tropical cyclone early on January 17 as NASA's Aqua satellite passed overhead and captured its birth. When Aqua passed over newborn Tropical Cyclone Deliwe on January 17 at 10:55 UTC/5:55 a.m. EST  the MODIS instrument or Moderate Resolution Imaging Spectroradiometer took a picture of it. Deliwe was previously known as Tropical Depression 09S. In the MODIS image bands of thunderstorms stretched west...

The intensity of tropical cyclones hitting East Asia has significantly increased over the past 30 years, according to a new study published today. The coastlines of China, Korea and Japan in particular have experienced increasingly stronger cyclones, which the researchers have attributed to increasing sea surface temperatures and a change in atmospheric circulation patterns over the coastal seas. According to the study, the changes in sea surface temperature and wind flows meant that...

NASA Sees Wind Shear Affecting Cyclone Ian
2014-01-14 07:47:23

NASA Tropical Cyclone Ian has been battered by wind shear and infrared imagery from NASA's Aqua satellite revealed that the bulk of the precipitation has been pushed east and southeast of the storm's center. On January 13 at 0900 UTC/4 a.m. EST, Tropical Cyclone Ian's maximum sustained winds were near 65 knots/74.8 mph/120.4 kph, just at hurricane-strength. Just a day before, Ian's maximum sustained winds were near 80 knots/148.2 kph/92.0 mph. Ian is moving to the southeast at 14...

Soap Bubbles Used To Predict Cyclone Intensity
2014-01-08 08:38:25

Laboratoire Ondes et Matière d'Aquitaine Could soap bubbles be used to predict the strength of hurricanes and typhoons? However unexpected it may sound, this question prompted physicists at the Laboratoire Ondes et Matière d'Aquitaine (CNRS/université de Bordeaux) to perform a highly novel experiment: they used soap bubbles to model atmospheric flow. A detailed study of the rotation rates of the bubble vortices enabled the scientists to obtain a relationship that accurately describes...

Tropical Storm Alberto Timeline
2012-05-24 08:26:54

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...

Weather Educartion: Impacts Of The Canadian High Pressure Center
2012-12-29 11:43:39

The Canadian High pressure center shifts into the United States throughout the year and has a major impact on the weather from season to season. In the summer when this high pressure moves in, the temps usually cool off by about 10-15 degrees. For example:  if the temp was 91F in Fargo, it would cool down into the 70s once this high moved in. The high also creates drier weather. In winter when this system moves in the weather pattern is the same in that the temps will drop and the air...

Polar Watch For Aug 29- Sept 4
2012-09-05 08:00:17

A look at the temps from the 4th show that another colder pocket of air is moving into the region. Aug 29: The max temps warmed to 1C, while the overnight lows dropped to 0C. Aug 30: A burst of colder air was over the polar cap as high temps only made it to -3C, and the overnight lows dropped to -6C. Aug 31: Brought a touch of warmer air back into the region as high temps rose back to 1C, while the overnight lows hit -2C. September 1: High temps again rose to 1C, while overnight lows...

Weather Pack For September 6, 2012
2012-09-06 08:00:38

Today on Weather Pack we are going to examine the surface wind around a mature low pressure system, which means that the low pressure has an occluded front associated with it. Yellow Star: The forecasted surface winds would be out of the Northwest as the flow behind the low is counter-clockwise. Green Star: Anyone that is forecasting for the green star would be looking at the winds coming from the South-Southeast just right ahead of the warm front of the low pressure system. Red...

Upper Air Map Identification for July 6, 2012.
2012-07-06 12:00:10

Looking at the upper air map for the entire region from Alaska to the Atlantic Ocean we can identify a few significant features. The first is the deep low height center over Alaska, this is telling us that at 30,000ft the air is rising upwards allowing for the surface low to still be gaining strength. Also if you look to the west of that closed low you will see what is referred to as a jet max getting ready to enter the base of the low height center. This will further amplify the low...
