    The Role of the Western Arabian Sea Upwelling in Indian Monsoon Rainfall Variability. Summer Monsoon Blows from the South and Southwest, and across the Arabian Sea, the Bay of Bengal, and apart of the Indian Ocean. As the warm air over India rise, the cooler air over the water flows to equalize the air pressure.

    Monsoon—evidence from deep-sea cores, northwest Arabian Sea Graham B. Shimmield, Stephen R. Mowbray and Graham P. Weedon ABSTRACT: The Indian summer Southwest Monsoon plays an important part in influencing, and regulating, the productivity and sedimentation in the northwest Arabian Sea at the present day, by driving coastal upwelling.   During summer, the main bloom areas were along the coasts of the Arabian Sea, in the open Arabian Sea, around Sri Lanka up to the southwestern Bay of Bengal, in the northwest Bay of Bengal, along the coast of Indonesia, and in a subtropical band centered on °S.

Based on aerological observations over the Arabian Sea and adjoining north Indian Ocean, taken on board USSR research vessels during MONEX‐, patterns of vergence of air and water vapour fluxes are studied. The influence of the Arabian Sea on the fluctuations in intensity of the summer monsoon over the west coast of India is shown.

An analysis of upwelling off the south-east Arabian coast during the summer monsoon and vertical mass transports off the southeast Arabian coast during the summer monsoon are calculated. extending at least km offshore and paralleling the Arabian coast for over km.

Upwelling is most intense in a narrow band adjacent to the coastCited by: 3. An analysis of upwelling off the south-east Arabian coast during the summer monsoon.

The observations on the Local Temperature Anomaly at different depth levels exposed that, at the surface, the upwelling features was limited to the SW coast of India during the summer monsoon.

As indicated by the calculations, upwelling occurs throughout a region extending at least km offshore and paralleling the Arabian coast for over km. Upwelling is most intense in a narrow band adjacent to the coast.

Because of the great. Off the SW coast of India, upwelling starts even before the onset of the summer monsoon and continues till it ends in September. Major features of the upwelling are the upward displacement of the 20 oC isotherm by nearly m, the invasion of the shelf off the west coast by nutrient-rich waters and the reduction of SST.

eastern Arabian Sea. During the summer monsoon from May to September the eastern coast of southern India during summer monsoon (Chl-a along °N and °N is 1 mg/m³ dec⁻¹, UIwind and. The upwelling along the Somalia and Oman coasts starts in late spring, peaks during the summer monsoon, and strongly cools the sea surface temperature (SST) in the western Arabian Sea.

They restrict the westward extent of the Indian Ocean warm pool, which is the main moisture source for the monsoon rainfall. Studies based on sediment records, sea-surface temperature and wind suggest that upwelling along the western coast of Arabian Sea is strongly affected by the Indian summer Monsoon.

We examine this relationship directly in an eddy-resolving global ocean simulation STORM driven by atmospheric reanalysis over the last 61 years. With its very high spatial resolution (10 km), STORM allows us to. () discussed the relation between Arabian Sea SST and Indian monsoon rainfall variability and highlighted the lack of accurate past observations.

During –summer SST over the western Arabian Sea is, 1 In the present article, to avoid confusion when using the de-generated word “monsoon,” we discuss monsoon rainfall. FIG. Quantitative analysis of the late Cenozoic planktonic foraminiferal record from western Arabian Sea Site re-vealed long term trends in the history of oceanography and climate.

The modern western Arabian Sea surface waters are highly influenced by the monsoonal wind system. Summer upwelling, a result of southwestern winds, occurs along the.

During the summer monsoon, strong, steady winds push water on the sea surface toward land. In response to the intensified winds and resulting surface-water movement, cooler waters rise up from the ocean depths. Although temperature variations still exist during. coast of India during the onset of summer monsoon [2] and in shallow water location in the north Indian Ocean during the summer monsoon [3] were mainly swells ar-riving from south and south-west direction.

Studies based on sediment records, sea-surface temperature and wind suggest that upwelling along the western coast of Arabian Sea is strongly affected by the Indian summer Monsoon. We examine this relationship directly in an eddy-resolving global ocean simulation STORM driven by atmospheric reanalysis over the last 61 years.

Near the coast, upwelling does this. In the central Arabian Sea, the mixed layer deepens and cools primarily due to wind-driven entrainment of cooler, nutrient rich water across its base in the summer monsoon.

In the winter monsoon, the surface water in the central Arabian Sea is made more dense (cooler and saltier) by surface cooling and. Along the coast of the Arabian Peninsula, estimates using wind and hydrographic data suggest that in a region of km along the coast and km offshore, 8×10 6 m 3 /s water upwells through the 50 m level with maximum vertical velocities of 2×10 −5 m/s during the southwest monsoon (Smith and Bottero, ).

In September the front is. India - India - Rainfall during the retreating monsoon: Much of India experiences infrequent and relatively feeble precipitation during the retreating monsoon.

An exception to that rule occurs along the southeastern coast of India and for some distance inland. When the retreating monsoon blows from the northeast across the Bay of Bengal, it picks up a significant amount of moisture, which is.

The modern western Arabian Sea surface waters are highly influenced by the monsoonal wind system. Summer upwelling, a result of southwestern winds, occurs along the coast of Somalia which produces distinct. In particular, discriminating the post-middle Miocene global cooling from the monsoon upwelling cooling is critical, but poorly understood due to the lack of adequate constraints for monsoonal upwelling.

Here we present new middle to late Miocene biomarker-based reconstructions of sea-surface temperature (SST) for the western Arabian Sea.
