WebFeb 28, 2024 · How do the doldrums and trade winds affect our weather? The Sun shines very directly at the equator, creating very intense heat. The heat warms the air and causes some ocean water to evaporate, meaning air in the doldrums becomes warm and moist. http://mtc-m21d.sid.inpe.br/col/sid.inpe.br/mtc-m21d/2024/02.09.12.28/doc/atmosphere-14-00064.pdf
