It is now mid-November and the Earth’s axis continues to tilt toward the ecliptic north pole bringing more and more of the southern hemisphere face to face with the Sun, as our planet approaches the winter solstice on 21 December 2014, in a cycle already repeated millions of times.

Under the influence of this annual dance tropical cyclone activity increases and peaks in the region of the Earth facing the Sun, as the atmosphere and oceans get warmer and other contributors to cyclogenesis influenced by the Sun’s energy coalesce in various basins.

Today is Sunday 16 November 2014 and there are no tropical cyclones active anywhere in the northern hemisphere, however we already see cells of disturbed weather on both sides near the equator, but mainly in the southern hemisphere There is in fact one large tropical wave around a center of low pressure over the southern Indian Ocean, which is already showing signs of potential cyclonic development.

Satellite images and date collected by satellites show a mostly quiet western hemisphere, in terms of tropical cyclone activity, and progressively cooler surface waters in the northern Pacific and Atlantic oceans.

UPDATE AS OF 0200 UTC 17 NOVEMBER 2014:
The tropical wave in the southern Indian Ocean has now strengthened to Tropical Storm ADJALI to the west of Diego Garcia. While this cyclone has moved little over the past few hours it is tracking mainly toward the southeast.
