Hurricane season 2007

The start of the 2007 hurricane season is still more than 4 months away, but things are moving on a global scale that give a hint of things to come.

The 2006 season was unusually quiet, which is attributed to the El Nino phenomenon. This means that the temperatures in the Pacific, west of South America, are above normal. As a result, the circulation within the atmosphere is altered, and works against the formation of hurricanes in the Atlantic, but in favour of them forming in the Eastern Pacific.

Over the past few weeks, the temperatures of the seas of the Pacific have receded from their relative highs towards normal, a trend expected to have been completed by June. This would suggest that the 2007 season will see an average number of tropical cyclones in the Atlantic. For the moment, the waters of the Atlantic appear to be cooler than expected at this time of year, so that might work against the 2007 hurricane season being an intense one.

I should stress that this is not the official view, and only my personal interpretation of data, as presented by Dr Jeff Masters, senior meteorologist at Weather Underground. A formal outlook of the 2007 season will be presented later this spring.

  1. Very interesting. I dont' know much about the subject of Global Warming, it is little, but it seems although everyone here is happy about the mildness of weather and some of the unusual qualities of it, I beleive mother nature will take back what it gives, and that isn't good :(
