Historical Examples. 1  The present writer has collected several hundred local wind namesâand is constantly adding to the list. 2  Because local wind systems dominate the trade winds, these deserts are less stable than other deserts.
Local Winds. Local winds are small scale convective winds of local origin caused by temperature differences. Local terrain has a very strong influence on local winds, and the more varied the terrain, the greater the influence. Convective winds are all winds - up, down, or horizontal - that develop as a result of local temperature differences.
