# Long description

This is a schematic of the Earth as a circle divided into horizontal bands. From the north pole working downwards to the south pole these bands are: Polar High with wind vectors sloping down to the left; Sub-polar High – no wind vectors; Westerlies (temperate zone) with wind vectors sloping up to the right; Sub-tropical high – no wind vectors; N. E. Trades (tropical zone) with wind vectors sloping down to the left; Doldrums low, being a band halfway up, around the equator – no wind vectors; S. E. Trades (tropical zone) with wind vectors sloping up to the left; Sub-tropical high – no wind vectors; Westerlies (temperate zone) with wind vectors sloping down to the right; Sub-polar low – no wind vectors; Polar high with wind vectors sloping up to the left.
