The northwest wind in the lower valley of the Tigris and Euphrates and the Persian Gulf. It may set in suddenly at any time, and generally lasts from one to five days, dying down at night and freshening again by day; however, in June and early July it continues almost without cessation (the “great” or “forty-day” shamal). Although the wind rarely exceeds 13 m s<sup>−1</sup> (30 mph), it is very hot, dry, and dusty. The sky is cloudless but the haze is often so thick as to obscure the land, making navigation dangerous.

Hanging protuberances, like pouches, on the undersurface of a cloud. This supplementary cloud feature occurs mostly with cirrus, cirrocumulus, altocumulus, altostratus, stratocumulus, and cumulonimbus; in the case of cumulonimbus, mamma generally appear on the underside of the anvil (incus). See cloud classification.

In the Tropics or subtropics, rainy seasons that recur annually or semiannually at about the time that the sun is most nearly overhead (at zenith).
Within a few degrees of the equator, two such periods of heavy rains may occur annually, the equinoctial rains. Farther from the equator, these blend into a single annual summer rainy season.
