Sea Surface Temperature: the anomaly of August 2015

The temperature range

Sea surface temperature (SST) is the temperature of the top millimeter of the ocean’s surface. The map displays the SST variation during the period of August 2015. Warmer colors such as yellows and reds represent higher temperatures, while cooler ones such as green and blue represent lower temperatures. A SST anomaly is a departure from average conditions. These maps compare temperatures in a given month to the long-term average temperature of that month from 1992 through 2009. Blue shows temperatures that were cooler than average, white shows near-average temperatures, and red shows where temperatures were warmer than average. Some sea surface temperature anomalies are simply transient events, not part of a specific pattern or trend. Other anomalies are more meaningful. SST was higher than normal was observed throughout most of the South-Western Indian Ocean (SWIO).

Warming ?

In the broader south indian Ocean, the sea surface temperature is higher than normal. In general, as seen from the climatology, August SST is warmer at the north and colder at the south of Madagascar. SST east Madagascar coast tends to be warmer (0.2°C above normal) and the central western coast remains near normal. However, the Mozambique channel (the open waters of west coast) appears to be higher than normal (1.5°C) in the north-west and the southern part of the island (0.6°C).
