The equator is an intensely heated throughout the year . Due to the intense heating the air in this region becomes warm and light and it rises above creating a partial vacuum .(As you know vacuum leads to decrease in air pressure) As a result a region of permanent low pressure is created called the equatorial low pressure belt.
The Norwegian explorer, Fridtjof Nansen proved the Arctic was a deep polar ocean with a drifting ice cap in the late 1890's. Previously there were ideas that within the belt of ice, open shallow water, perhaps land surrounded the North Pole.

Doldrums
The uneven heating of the earth produces pressure belts. these belts occur at about every 30 degrees latitude. The rotation of the Earth flings the bulk of the air creating an area of low pressure belt in this region.
The Subpolar Low-Pressure Belt lies along the polar jet stream. It is found between 50 and 70 degrees North latitude. It consists of the Aleutian and Icelandic lows.
1.Thermal pressure belts Equatorial low pressure belt lies with 5 degrees of north and south of equator.(DOLDRUMS) b.Polar high pressure belt are formed around the north and south polar regions. 2.Other pressure belts a.Sub tropical high pressure belts are formed due to sinking of equatorial air that cools on 30 degrees near north and south. (HORSE LATITUDES) b.Sub-Polar temperate low pressure belts are formed near the arctic and antarctic circles. Here the cold winds meet the warm westerlies formed at 60 degrees.
the reason is the higher the latidue is the colder the weather it gets
temperate cyclones causes rainfall. westerlies are strong winds..............

High or low pressure lies along the subtropical jet stream, depending on the time of year. The pressure gradient follows the path of the jet stream.
