Jan 21, 2025 · Ocean surface circulation is wind-driven. In the monsoon zone, surface circulation reverses every half year and features two opposing gyres (i.e., semi-closed current systems exhibiting spiral motion) that are separated by the Indian subcontinent.

The Indian Monsoon Current refers to the seasonally varying ocean current regime found in the tropical regions of the northern Indian Ocean. During winter, the flow of the upper ocean is directed westward from near the Indonesian Archipelago to the Arabian Sea.

Jan 16, 2025 · By early October, variable winds are very frequent everywhere. At the end of the month, the entire Indian region is covered by northerly air and the winter monsoon takes shape. The surface flow is deflected by the Coriolis force and becomes a northeasterly flow.

Dec 26, 2014 · Map of seasonal monsoon trade winds on the Indian Ocean: summer winds in red, winter in blue. The route those early Greeks stumbled across had already been used for centuries by sailors traveling between India and East Africa, trading ivory and various metals.

The Indian Ocean and its surrounding atmosphere still hold their heat, causing cold wind to sweep down from the Himalayas and Indo-Gangetic Plain towards the vast spans of the Indian Ocean south of the Deccan peninsula. This is known as the Northeast Monsoon or Retreating Monsoon.

Mariners and merchants used knowledge of monsoon winds to move across the Indian Ocean region. Monsoon winds are the seasonal change in the direction of a region’s winds. In tropical areas, monsoon winds cause wet and dry seasons. Monsoon winds are strongest in the Indian and Pacific Ocean regions.

North-east monsoon winds blow from land to the ocean during winter season in the northern hemi­sphere and thus westward blowing north-east monsoon currents are produced between Andman and Somali (fig. 29.4). This current flows to the south of 5°N latitude.

Jan 15, 2016 · The currents in the northern portion of the Indian Ocean change their direction from season to season in response to the seasonal rhythm of the monsoons. The effect of winds is comparatively more pronounced in the Indian Ocean.

Jan 1, 2001 · In this paper, we review observations, theory and model results on the monsoon circulation of the Indian Ocean. We begin with a general overview, discussing wind-stress forcing fields and their anomalies, climatological distributions of stratification, mixed-layer depths, altimetric sea-level distributions, and seasonal circulation patterns ...

Apr 23, 2021 · If the west side of the Indian ocean happens to be warmer, the monsoon winds in the low-lying Findlater or the Somali jet stream are able to soak up more moisture resulting in stronger subsequent summer monsoon rainfall. This situation is …
