Westerly monsoon winds lie in its equatorward portion while easterly trade winds exist poleward of the trough.
12.
This leads to slow equatorward flow throughout most of a subtropical ocean basin ( the Sverdrup balance ).
13.
During magnetospheric disturbed conditions, this conductivity enhancement becomes much larger, and the auroral regions move equatorward.
14.
In tropical northern Panthalassa trade winds created westward flows while equatorward flows were created by westerlies at higher latitudes.
15.
Analogously, near the surface, the equatorward return flow is turned to the west by the Coriolis effect.
16.
These resulting surface winds, with both an equatorward and a westward component, are referred to as the trade winds.
17.
Cities near the equatorward boundary of this zone include Hong Kong, Hanoi and Taipei while Qingdao is near the northern boundary.
18.
The AE index indicates the intensity of geomagnetic substorms except during a major geomagnetic storm when the auroral zones expand equatorward from the observatories.
19.
Upper level analysis indicated that the dual channel outflow to the poleward and equatorward directions had been instrumental in the system maintaining its intensity.
20.
The equatorward migration of the subtropical ridge during the cold season is due to increasing north-south temperature differences between the poles and tropics.
