TLDR
In this article, the authors have discussed some of the observed features of the Arabian sea summer monsoon, such as the formation of a low-level highspeed aircurrent, strengthening of the intertropical convergence zone over northeastern Arabian sea and formation of the secondary convergence zones over southeastern Arabian sea, changing patterns of cloud distributions, formation of double cloud bands and rainfall discontinuities along the west coast of India.Abstract:
Some of the observed features of the Arabian sea summer monsoon, such as the formation of a low-level highspeed aircurrent, strengthening of the intertropical convergence zone over northeastern Arabian sea and formation of a secondary convergence zone over southeastern Arabian sea, changing patterns of cloud distributions and formation of double cloud bands over eastern Arabian sea and rainfall discontinuities along the west coast of India between July and August are discussed in relation to possible complex transformations of airmasses that cross the Arabian sea with a continually changing pattern of surface temperature during period May through August. It is hypothesised that following coastal upwelling in Somalia and Arabia during late May or early June, a wedge of cold water is advected across central Arabian sea by the southwestmonsoon current and that it is the feed-back effect of this advection upon the atmosphere that may be largely responsible for the observed monsoon features.

On the possible mechanisms of the evolution of a mini‐warm pool during the pre‐summer monsoon season and the genesis of onset vortex in the South‐Eastern Arabian Sea
R. R. Rao,R. Sivakumar +1 more
TL;DR: In this article, the authors examined the possible mechanisms for the observed seasonal build-up of this mini-warm pool, utilizing all the available monthly mean climatologies of surface wind field, surface heat fluxes, near-surface thermohaline fields, near surface circulation, and mean sea level as monitored by satellites and by some of the recent model solutions on the Arabian Sea circulation.

The monsoonal heat budget of the hydrosphere-atmosphere system in the Indian Ocean sector
TL;DR: In this article, the heat budget of the combined hydrosphere-atmosphere system in the Indian Ocean sector (30°N to 30°S, 30°-120°E) is studied on the basis of surface ship observations and subsurface temperature casts to 400 dbar, analyses of the atmospheric heat and moisture transport in the layer surface to 100 mbar, published estimates of precipitation, and satellite measurements of net allwave radiation at the top of the atmosphere.

A major low-level air current near the Indian Ocean during the northern summer
TL;DR: The high-energy flow, in the form of low-level southerly jet streams which have been reported earlier over Kenya, is only one part of a much more extensive current of air which flows rapidly around the western half of the Indian Ocean during the northern summer as mentioned in this paper.

Eddy Motion in the Atmosphere
TL;DR: In this paper, the effect of a system of eddies on the velocity of the wind and on the temperature and humidity of the atmosphere was investigated, and it has been known for a long time that the retarding effect of the surface of the earth on the wind must be due, in some way, to eddy motion.

Water masses and patterns of flow in the Somali Basin during the southwest monsoon of 1964
TL;DR: Closely spaced hydrographic sections made during August-September 1964 in latitudes 3°S-12°N, and between the East African coast and longitude 56°E, define in detail a complex structure of water masses in the Somali Basin under the southwest monsson Reference to observations made elsewhere in the Indian Ocean permits clear identification of the source waters responsible for this structure as mentioned in this paper.
