• W2361018424 abstract "The long-term variation of the Tropical Easterly Jet(TEJ) and its relationship with the distribution of rainfall in Asian and African monsoon regions are studied using the National Center for Environmental Prediction/National Center for Atmospheric Research(NCEP/NCAR) reanalysis data from 1958 to 2002.TEJ is denoted by 150-100 hPa zonal wind,and an index(TEJI) is defined to measure the variability of TEJ.It is shown that TEJ covers large tropical areas extending from the date line to the west coastal regions in Africa.Its core is located in 10°N-15°N in southern Indian peninsula with the maximal speed larger than 30 m/s,and the mid-line lies around 70°E,its east being the entrance region and its west the exit region.There are two branches of the TEJ axis in the entrance region,the southern one in 0°-10°N lying northwest-southeast and the northern one in 10°N-20°N lying northeast-southwest.Westerly prevails in the mid-latitudes,while easterly is limited in the lower-latitude areas with its maximal intensity in the layer of 150-100 hPa.The zonal wind shear between the upper and lower troposphere is very significant in the Asian-African monsoon regions,but easterly occupies almost the entire troposphere in the tropical oceans.TEJ has intraseasonal oscillation(ISO) with periods of both 40-60 days and 20-30 days,but the latter is not significant.The disturbance starts to travel eastward and westward from the dateline along 7.5°N-12.5°N,and it starts to travel northward from the equator along 70°E.TEJ has interannual variation with periods of 2-4 years and 7-10 years.Generally it is negatively correlated with ENSO: TEJ weakens in warm events and strengthens in cold events.Compared to La Nia years,easterly is weaker in El Nio years.TEJ has obvious interdecadal variation,and 1978 is its climate jump year.It is a strong TEJ period before 1978,and TEJ weakens significantly after the climate jump. In Asia and central Africa,the primary rainfall,convection,upper divergence and ascending motion appear on the right side of the entrance region and the left side of the exit region of TEJ.However this is not the case in West Africa.There are two opposite vertical circulations in the entrance region and the exit region,which is closely associated with the distribution of rainfall.In the entrance region,the vertical circulation and rainfall in strong TEJ years are stronger than those in weak TEJ years;however,their differences between strong and weak TEJ years are not obvious in the exit region,which may be explained as follows: since the contour is sparser in the exit region than in the entrance region,the decreasing speed of easterly is smaller,then the geostrophic deviation is smaller,and the vertical circulation is weaker.Therefore,it is easily influenced by the vertical circulations produced by other factors,and the differences between strong and weak TEJ years are not obvious in the exit region." @default.
