Climate Patterns (IMAGE) University of Wisconsin-Madison Caption The Indian Ocean Dipole is one example of repeated and predictable climate patterns that create opposite extremes over large regions. When waters off of East Africa warm, it sets up heavy rains in some regions and drought in others. When East African waters cool, those rainfall patterns reverse. Plants and animals likely respond to these regional changes in climate. Credit Illustration by E.
