| Description: Relatively complex pattern Related to global wind and pressure patterns High pressure regions Subsiding air Divergent winds Dry conditions e.g., Sahara and Kalahari deserts Related to global wind and pressure patterns Low pressure regions Ascending air Converging winds Ample precipitation e.g., Amazon and Congo basins Related to distribution of land and water Large landmasses in the middle latitudes often have less precipitation toward their centers Mountain barriers also alter precipitation patterns Windward slopes receive abundant rainfall from orographic lifting Leeward slopes are usually deficient in moisture Picture Stats: Views: 439 Filesize: 1.41MB Height: 712 Width: 1350 Source: https://biology-forums.com/index.php?action=gallery;sa=view;id=39863 |
