When the polar vortex is weak, high pressure zones of the mid latitudes may push poleward, moving the polar vortex, jet stream, and polar front equatorward.

South of Cap Blanc, upwelling is limited to winter and spring due to the northward migration of the Azores high during summer, which is responsible for driving equatorward winds.
33.
When the Arctic pattern is at its weakest, subtropic air masses can intrude poleward causing the Arctic air masses to move equatorward, as during the Winter 1985 Arctic outbreak.
34.
Deep ocean basins generally have a non-symmetric surface current, in that the eastern equatorward-flowing branch is broad and diffuse whereas the western poleward flowing branch is very narrow.
35.
Strong slopes with equatorward aspects tend to have soil organic matter levels and seasonal influences similar to level slopes at lower elevation whereas poleward aspects have soil biological processes that are temperature dependent.
36.
Because air must conserve its angular momentum, this flow configuration induces a cyclonic gyre equatorward and westward of the storm center and an anticyclonic gyre poleward and eastward of the storm center.
37.
When Jelawat was drifting westwards by a weak steering environment on September 22, it intensified into a severe tropical storm for excellent equatorward eyewall with excellent equatorward outflow and good poleward outflow.
38.
When Jelawat was drifting westwards by a weak steering environment on September 22, it intensified into a severe tropical storm for excellent equatorward eyewall with excellent equatorward outflow and good poleward outflow.
39.
But a " high amplitude " upper-wind pattern, which has extreme poleward swings of warm air and dramatic equatorward bulges of cold air, has dominated North America and the Atlantic.
40.
Runoff caused by the cyclone enhanced available nutrients in the Bay of Bengal, supplementing the already present equatorward ocean current and resulting in an increase in chlorophyll a and particulate organic carbon in the region.
