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...

NASA's Solar Dynamics Observatory Sees Giant Sunspots
2014-01-08 07:21:33

NASA An enormous sunspot, labeled AR1944, slipped into view over the sun's left horizon late on Jan. 1, 2014. The sunspot steadily moved toward the right, along with the rotation of the sun, and now sits almost dead center, as seen in the image above from NASA's Solar Dynamics Observatory. Sunspots are dark areas on the sun's surface that contain complex arrangements of strong magnetic fields that are constantly shifting. The largest dark spot in this configuration is approximately two...

NASA Sees New Tropical Depression Forming Near Australia's Kimberly Coast
2013-12-27 12:16:40

NASA Low pressure System 98S appears ripe to form into Tropical Cyclone 05S as NASA satellite imagery is showing some hot towering clouds in the storm and heaviest rains south of the center. System 98S is expected to become a tropical depression on Saturday, December 28, and alerts are already in effect. NASA and the Japan Aerospace and Exploration Agency's Tropical Rainfall Measuring Mission or TRMM satellite passed over developing System 98S on December 26 at 1140 UTC/6:40 a.m. EST...

redOrbit Meteorologist Joshua Kelly Big Story Weather from December 25: A few snow showers moved across the Great Lakes and extreme Northeast during the day, yesterday. Colder air pushed into the Southern Plains, Gulf Coast and Southeast behind the frontal boundary, while warmer air surged northward into the Rockies and portions of the Plains ahead of the next clipper system. Big Story Weather Discussion for December 26: Surface Map 11AM: High pressure settling in over the...

redOrbit Meteorologist Joshua Kelly Big Story Weather from December 23: Another cold night across many parts of the US from the Northern Plains into the Gulf Coast. Showers continued along the East Coast but cleared out late last night. Temps fell to around -20F along with wind chill values near -40F over portions of the Northern Plains. Big Story Weather Discussion for December 24: Surface Map 11AM: High pressure over the Tennessee River Valley will make for another cold...

redOrbit Meteorologist Joshua Kelly Big Story Weather from December 20-22: A very active weekend was seen across a good portion of the country. Heavy rainfall was found from the Ohio River Valley to Gulf Coast with some places seeing between 4-9 inches. Heavy snowfall was seen over portions of the Western Lakes with some place seeing 3-7 inches. Record setting warmth hit the Gulf Coast with places pushing near 80F, while cold weather hit over the Northern Rockies and Plains with places...

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

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...
