The equatorial low and subtropical high were areas of light and variable winds which caused difficulties for mariners in the days of sailing ships. The equatorial low is an area of low pressure near the equator which causes light and variable winds, while the subtropical high is an area of high pressure at around 30 degrees latitude which also causes light and variable winds. These conditions made it difficult for sailing ships to make efficient progress on their voyages.
