For example, water near The temperature that it feels like outside due to the air temperature and wind speed is called the Wind Chill.. our atmosphere and oceans, which means that we are all connected. Many daily weather patterns depend on wind. Now we do.. Wind results from a horizontal difference in air pressure and since the sun heats different parts of the Earth differently, causing pressure differences, the Sun is the driving force for most winds. At the horse latitudes some of the sinking air travels back toward the equator. suggest that the relationship between global warming and precipitation patterns is not always so straightforward. Various human activities and environmental phenomena can influence wind patterns, including: Wind affects various Earth system processes and phenomena, including: Can you think of additional cause and effect relationships between wind and other parts of the Earth system?
