Constant heat and humidity to the north and south create a continuous cycle of warm updrafts. These create a band of low pressure, leading to thundery weather, with a steady supply of cumulonimbus clouds, causing the extreme wet and dry seasons found in equatorial countries. 2, record 1, English, - thundery%20weather

The world's biggest Low is caused by hot air rising near the equator(it is called the Equatorial Low). Its position moves north and south during the year as it follows the movement of the overhead sun and the latitude of greatest heating. The Equatorial Low is the heat ’engine’ that powers the entire global circulation. Cloud and rain are produced by rising air, making the Equatorial Low also the world's main rain-producing area and the place of the great tropical rainforests. 2, record 8, English, - equatorial%20low

C'est à partir de cette eau chaude que se forment les nuages qui entraînent les moussons. Cette masse d'eau chaude est gardée en place grâce aux alizés, vents soufflant des hautes pressions subtropicales vers les basses pressions équatoriales.
