We still know very little about climate on earth. Global Warming is a hoax and Climate Change is a religion!
"... The windless equatorial region of the ocean, known as “the doldrums”, became so famous for stranding boats in the Age of Sail that the word has become part of our vernacular. ...
She examined the link between wind speeds and the Intertropical Convergence Zone (ITCZ) – a band of low-pressure air near the equator, which is caused by rising hot air.
The results showed that low wind speeds occurred in about 5% of the region at any given time, although their frequency varied by season.
These low wind speeds also coincided with clear, rainless, weather and cooler temperatures – conditions that imply sinking air masses, rather than rising air. ..."
From the abstract:
"The doldrums are regions of low wind speeds and variable wind directions in the deep tropics that have been known for centuries. Although the doldrums are often associated with the Intertropical Convergence Zone (ITCZ), the exact relationship remains unclear. This study re-examines the relationship between low-level convergence and the Atlantic doldrums. By analyzing the frequency distribution of low wind speed events in reanalysis and buoy data, we show that the doldrums are largely confined between the edges of the ITCZ marked by enhanced surface convergence. While the region between the edges is a region of high time-mean precipitation, low wind speed events occur in the absence of precipitation. Based on these results, we hypothesize that low wind speed events occur in regions of low level divergence rather than convergence."
