Figure 2 illustrates the steady southerly and easterly spread of the epizootic between the early cases in the third quarter of 2001 and the final quarter of 2002.
Most of them are detectable in the low tropospheric temperature field as cold troughs in the easterlies.
From pole to equator they are the polar easterlies, the westerlies and the trade winds.
Embedded within the deep easterlies, the depression tracked west-northwestward at 20mph km/h.
Downward motion of the easterlies is usually more irregular than that of the westerlies.
The polar easterlies are one of the five primary wind zones, known as wind belts, that make up our atmosphere's circulatory system.
Westerly winds are most frequent in the mid-latitudes while easterlies dominate the tropics.
A weak inverted wave in the easterlies is generally found underneath them, and they may also be associated with broad areas of high-level clouds.
