A bear can outrun a horse over short distances. On average, bears are capable of achieving speeds of 37 miles per hour, while horses gallop at speeds of 25 to 30 miles per hour.

Westerly winds are one of several types of winds that form at various latitudes and geographical regions around the world. Closer to the equator, prevailing winds are referred to as doldrums and are generally much less forceful than westerly winds. These winds may come from any one of the primary cardinal directions, although at times they are virtually nonexistent. Trade winds are winds that occur on latitudes up to 30 degrees north and south of the equator and blow predominantly from the east.

Air pressure and temperature are primarily responsible for generation of the various winds, and both play a big part in influencing the direction from which wind blows. At the equator, heat generated from the sun causes air to rise and form an area of low pressure that gives rise to moving air that may generate from various directions. Westerlies vary in strength and may change with seasonal weather patterns or with sudden changes atmospheric changes, such as storms and the presence or absence of fronts and other weather systems.
