Abstract: | Summary The western Himalayas receive higher precipitation than the eastern Himalayas during the winter season (December–March). This
differential pattern of winter precipitation over the Himalayas can be attributed to topography and to a higher frequency
of disturbances over the western Himalayas, which result in variations in the circulation features. These circulation features,
in turn, result in variations in the meridional transport of heat, momentum, potential energy, and moisture across the Himalayas
due to mean and eddy motion.
Significant meridional transport due to mean motion takes place in the upper troposphere at 300 hPa and 200 hPa. Transport
east of 100° E dominates the transport over the western Himalayas. The eddy transport of heat, momentum, and potential energy
is considerably smaller than that due to mean motion. Eddy transport magnitudes are smaller up to 500 hPa and increase rapidly
aloft to 300 hPa and 200 hPa. Eddy transport over the western Himalayas is greater than over the eastern Himalayas. |
