doldrums

doldrums or equatorial belt of calms, area around the earth centered slightly north of the equator between the two belts of trade winds. The large amount of solar radiation that arrives at the earth in this area causes intense heating of the land and ocean. This heating results in the rising of warm, moist air; low air pressure; cloudiness; high humidity; light, variable winds; and various forms of severe weather, such as thunderstorms and squalls. Hurricanes originate in this region. The doldrums are also noted for calms, periods when the winds disappear, trapping sailing vessels for days or weeks.

The Doldrums (often capitalized when referring to the geographic region) is an area of the Atlantic Ocean and the Pacific Ocean affected by the Intertropical Convergence Zone, a low-pressure area around the equator where the prevailing winds are calm. The low pressure is caused by the heat at the equator, which makes the air rise and travel north and south high in the atmosphere, until it subsides again in the horse latitudes. Some of that air returns to the Doldrums through the trade winds. This process can lead to light or variable winds and more severe weather, in the form of heavy squalls, thunderstorms and hurricanes.

This region is also noted for calm periods when the winds disappear altogether, or are light and shifting. Hurricanes originate in this region. Because of the unpredictable weather patterns, the Doldrums became notorious with sailors because this region's periods of deadly calm could trap ships for days or weeks on end as they waited for enough wind to power their sails.

In colloquial usage, "being in the doldrums" refers to being in a state of listlessness, despondency, inactivity, stagnation, or a slump.

Doldrums

Doldrums occur near the equator.

All in a hot and copper sky,
The bloody Sun, at noon,
Right up above the mast did stand,
No bigger than the Moon.

Day after day, day after day,
We stuck, nor breath nor motion;
As idle as a painted ship
Upon a painted ocean.

the doldrums have 5 long winds long that means it could move 5 football fields
