Quick Reference

Type of weak trough in a tropical easterly airflow, which has a wavelength generally of 2000–4000 km. Such waves occur, for example, over W. Africa and in the Caribbean area where they develop in summer and autumn with a weak or absent trade-wind inversion, and in the central Pacific, when the equatorial trough is displaced northward. Disturbances in such waves often lead to tropical storms, which vary in intensity.
