Figure 5
(a), (b), (c) represent the Walker circulation (zonal and vertical winds are averaged between 25N-27N) during 30 August, 4th Sep and 6th September 2009 respectively while (d), (e) and (f) represent the Hadley circulation (meridional and vertical velocity fields are averaged between 80E-92E). The vertical velocity (x -100 hPa/s) is shown by shading where red (blue) indicates upward (downward) motions. Gray portions indicate the Tibetan Plateau.
