ReliefAnalysis Bulletin: Extreme Atlantic Anomalies

Here is a ReliefAnalysis bulletin for December 27, 2015.

Strong ocean temperature and atmospheric anomalies in the North Atlantic Ocean.

In the North Atlantic Ocean…

Extreme Sea Surface Temperatures are observed. In the Gulf Stream, a warm pool approximately 125 nautical miles Southeast of Halifax, Nova Scotia is registering a Sea Surface Temperature Anomaly of 8.7C, or 15.6F above normal. The actual water temperature is 66.2F, or 19C.

Approximately 255 Nautical Miles due east of that anomaly, is a cold Sea Surface Temperature Anomaly of negative 9.6F, or negative 5.3C. The actual water temperature is 44.9F, or 7.2C.

The Sea Surface Temperature difference between these closely-located anomalies in the Gulf Stream is 21.3F, or 11.8C.

Elsewhere…a ribbon of strong Sea Surface Temperature Anomalies of greater than 10F, reach from Cape Hatteras, North Carolina, northeast adjacent to the Continental Shelf to the Gulf of Maine, and terminating 310 nautical miles southeast of New Foundland. Within this zone, three additional cold water anomaly pools are located generally due east of George’s Bank.

The North Atlantic Cold Pool continues to stretch from between the Greenland and Canadian Coasts, as well as the Fram Straight, located between Greenland and Iceland, south to 35.57° N, 30.23° W, or Approximately 170 nautical miles southwest of the Azores. Atmospheric Features…an unusually strong zone of high pressure of 1028 millibars located near Bermuda is contributing to a deep tropical flow of warm air from the east reaching into the Caribbean, Gulf of Mexico, and Southeastern United States…contributing to strong temperature anomalies in the US Eastern Seaboard of over 20F, or 36F. In addition, a strong low pressure system off the southern coast of Greenland is producing a wave heights of 24.6 Feet, or 7.55 meters. Jet Stream Pattern – the 500 millibar Jetstream is flowing from the Gulf of Maine to the Azores, with a strong northern turn at the Azores nearly due North to Iceland, creating a warm ridge over Europe. Land Surface Temperature Anomalies are approximately 9F to 18F, or 5C to 10C above normal in Central Europe.
