    Abstract Wind observations from ships along the sea-lane off the Somali coast are used for estimating the seasonal increase in wind stress during the southwest monsoon. The stress has a relatively large maximum (˜ dyn cm-2) in the region between 8°N and 12°N during June, July, and August. Maximum values of the zonal wind stress curl occur. wind and stress, which they attributed in part to the existence of a coastal jet. Geernaert () attributed 30% of the variance in this wind stress angle to the effect of the heat flux, for the data considered. He showed that the sign of the angle between the wind stress and the mean wind vectors varied with that of the stability parameter, zL.

Generally, with the passage of a warm front, the temperature and humidity increase, the pressure rises, and although the wind shifts (usually from the southwest to the northwest in the Northern Hemisphere), it is not as pronounced as with a cold frontal passage.

Medium- to large-scale ocean dynamic features not nec- essarily associated with the SST front were also studied in FASINEX investigations.

Wind Stress Pattern. Wind stress on the sea surface is one of the most important driving forces for the oceanic circulation.

Wind stress generates small-scale surface waves first; through wave–wave interaction, energy is transferred in phase space, leading to surface waves of. The deviation of the wind stress vector from the wind direction at the air‐sea interface under low wind conditions was investigated based on direct eddy covariance flux measurements taken at a.

During winter, the offshore area is marked by very strong westerly stress exerted by the wind on the sea surface, with anticyclonic wind stress curl in an offshore band parallel to the coastline. During summer, the magnitude of the wind stress is reduced, and the region of strong westerly stress in the offshore area is lessened south of 35°S (Marshall & Speer, ).

April I. Hellerman COMPUTATIONS OF WIND STRESS FIELDS OVER THE ATLANTIC OCEAN S. HELLERMAN U.S. Weather Bureau, Washington, D.C. ABSTRACT A review is made of the procedures used by the Scripps Institute of Oceanography and by Hidaka in the first systematic attcmpts to compute the field of mean wind stress, 7, over the oceans by means of the resistance law.

The empirical formula proposed recently relating wind‐stress coefficient to wind velocity, C 10 = ( + U 10) × 10 −3, appears to be applicable even in formula also agrees with the correlation curve proposed earlier, C 10 = [κ/ln(1/aC 10 F 2)] 2, F = U 10 /(gZ) 1/2, where a = is the Charnock constant and Z = 10 m is the anemometer by: In physical oceanography and fluid dynamics, the wind stress is the shear stress exerted by the wind on the surface of large bodies of water – such as oceans, seas, estuaries and lakes.

It is the force component parallel to the surface, per unit area, as applied by the wind on the water surface. wind stress is presented in Eq. (9); (2) When the winds blow from land to the sea, negative surges occur.

Its relation with the wind stress is shown in Eq. (10), and most importantly; (3) It is found that the ratio of wind stress to either positive or negative surge is approximatelymeaning that one Pa (pascal = 1 N m -2) windFile Size: KB.

I Fred W. Dobson, Stuart D. Smith and Robert J. Anderson The wind profile in the atmospheric surface layer has a logarithmic form for neutral (adiabatic) stratification, Uz 4v = (u~/ic)ln(Z/zo) (1) In neutral conditions Uz = UZN.

The Rao and Murty studies showed that the large-scale steady state circulation pattern due to a uniform wind stress generally consists of a pair of counter-rotating gyres with downwind flow near the shores and upwindCited by: of the surface stress.

The large stress divergence near the surface might be due to thin boundary layers over the sea. The stress profile can also be distorted by momentum advection, particularly in the heterogeneous coastal zone (Fairall et al.

This strong wind forcing that is associated with the fast discharge of heat contents in the equator led to the short period and the weak intensity of ENSO occurred during the On the other hand, after the late s the relatively weak wind stress curl was accompanied with the long period and the strong intensity of ENSO.

Some typical models of the dependence of wind stess on waves are described in detail. Although there is no universally accepted theory and model, recent studies indicate that the wind stress strongly depends on the development state of sea waves, i.

Each of these forcing quantities have been used in ocean and atmospheric modeling. Wind velocity, pseudostress, and stress are all vector quantities with two horizontal components. Typically these components are given as east-wind (positive eastward), and north-south (positive northward).
