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 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
