Sea heat wave in the Atlantic, source Noaa
We have been talking about the situation in the Atlantic Ocean for the past few days Due to the much higher temperatures than normal, it is closer to September than June a sea. The Atlantic Major Cyclone Development Region (MDR) in June is the hottest on record. Not Home These days the surveyed area is active for the former Bret of the season. The temperatures reach 28°C, an ideal value also for the development of a tropical cyclone on the way to the Antilles. These values are well above those of 2005 and 2010, which were two very active hurricane seasons.
Bret is the third Atlantic storm of the year, after the formation of Tropical Storm Arlene on June 2 and an unnamed subtropical storm on January 16. June is typically the least active month of the Atlantic hurricane season, with only seven cyclones forming. Bret also joins the cluster of just four storms that formed in June, likely the most northeasterly. The current thermal trend would be in contrast to El Niño, which would instead reduce the possibility of cyclone development due to increasing wind shear.
Further north, water temperatures near the UK are even 6-8°C above average. These ocean heatwaves are sea surface temperatures that are above the 90th percentile for at least five days for that time of year. According to Noaa, the values are close to Ireland They would quantify it as a category 4 or 5 wave, which is extreme.
It is the aftermath of a blockade that has meant westerly winds have weakened, favoring warming near Britain, while weaker trade winds have favored warming over the tropical Atlantic.
