Final answer:
The subtropical high is also known as the horse latitudes, which are areas of high atmospheric pressure found around 30 degrees north and south latitude. They are characterized by dry and stable air, leading to minimal precipitation and light winds.
Step-by-step explanation:
Another name for the subtropical high is d. horse latitudes. The subtropical high is a large area of high pressure located at about 30 degrees north and south latitude in the Earth's atmosphere, which corresponds to locations known as the horse latitudes. These regions are characterized by dry and stable air due to descending air currents from higher in the atmosphere, which results in weak winds and thereby less frequent storms or rainfall. The related atmospheric conditions and biomes are influenced by these patterns, contributing to the creation of subtropical deserts as the dry air associated with subtropical highs descends.
The terms prevailing westerlies, doldrums, subpolar calm, and trades refer to different wind patterns found in other parts of the Earth's atmosphere. The prevailing westerlies are found in the mid-latitudes and play a crucial role in weather and climate, while the doldrums refer to areas near the equator with little to no wind, subpolar calm refers to the low-wind zone near the subpolar lows, and the trades or trade winds are the steady easterly winds found in the tropics.
