The westerlies are also much confused and interrupted by storms, whence their designation of stormy westerlies.
Towards the poles there is no obvious limit to the temperate zones, for the prevailing westerliesextend beyond the polar circles.
In winter the westerlies give moderate rains, chiefly on the south-western coast.
The limits between the prevailing westerlies and the outflowing winds from the pole ("easterlies") vary with the longitude and migrate with the seasons.
South of Africa and Australia, also, thewesterlies are remarkably steady and strong.
Marine climatic types are carried by the prevailing westerlies on to the western coasts of the continents, giving them mild winters and cool summers, abundant rainfall, and a high degree of cloudiness and relative humidity.
Their rainfall regime is alternately that of the westerlies and of the trades.
Winter is the season of maximum rainfall over oceans, islands and west coasts, for the westerlies are then most active, cyclonic storms are most numerous and best developed, and the cold lands chill the inflowing damp air.
The south temperate zone being chiefly water, the westerlies are but little disturbed there by continental effects.
The prevailing westerlies continue up into the margins of the polar zones.
As storminess decreased, the trades and westerlies probably became steadier, and thus carried to high latitudes more warm water than when often interrupted by storms.
Hence steadier westerlieswould make for lessened latitudinal contrasts in climate not only by driving more warm water poleward but by causing more polar water to reach low latitudes.
Strong seasonal winds disturb the normal planetary circulation of the trade winds in low latitudes and of the westerlies in middle latitudes.
Under such conditions, especially if the conception of the great subequatorial continent of Gondwana land is correct, the trade winds and the westerlies must have been stronger and steadier than now.
This interferes with the stable planetary winds, such as the trades of low latitudes and the prevailing westerlies of higher latitudes.
If the strength of the westerlies were increased because of broad lands in low latitudes, their efficacy in transferring heat would be correspondingly augmented.
The effect of such winds is illustrated by the way in which the westerlies prevent the Gulf Stream from warming the eastern United States in winter.
Now suppose that cyclonic storms should be greatly reduced in number so that in the zone of prevailing westerlies they were scarcely more numerous than tropical hurricanes now are in the trade-wind belt.
Temporarily this might indeed happen when a solar change first reduced the storminess and strengthened the westerlies and the surface currents.
At those dizzy heights the prevailing westerlies are in full force, blowing from eighty to two hundred miles an hour night after night and day after day.
These westerlies caught the storm exhalations, the streamers, and hurled them eastward at greater speed than the main body of the storm.
The westerly winds of the south blow with a force and a constancy which makes it impossible to compare them with the more variable westerlies of the north.
The Gulf Stream and the prevailing westerlies later gave English vessels the advantage on the return voyage.
Junks blown out to sea from China or Japan have been carried by the Kuro Siwo and the prevailing westerlies across the Pacific to our continent.
The above list will hopefully give you a few useful examples demonstrating the appropriate usage of "westerlies" in a variety of sentences. We hope that you will now be able to make sentences using this word.
