Climate and Ocean & Wind Patterns Heat Rises and Cold Sinks! Prevailing winds are global wind patterns that we can predict called trade winds near the equator o Why they happen: Air near equator heats up and rises towards poles (making wind) Cold air at poles sinks and goes towards equator (making wind) o winds in Northern Hemisphere curve clockwise o winds in Southern Hemisphere curve counter clockwise o Prevailing winds bring seasonal storms predictable weather Ocean Currents are moving streams of water that follow a pattern that we can predict o How they happen: water near equator heats up and rises towards poles Cold water at poles sinks and goes towards equator On the way the currents move around the continents o currents bring warm or cold air with them and affect the climate of places they pass
