The extension of the tropical depression over the southern Arabian Peninsula will cause an increase in seasonal thunderstorms in the coming days.

Arab Weather - Weather map analysis indicates a shift in the subtropical high pressure system away from the southern Arabian Peninsula, opening the way for the intertropical divide zone (ITCZ) to extend toward Yemen and parts of southwestern Saudi Arabia. As a result, weather activity associated with seasonal rains is expected to intensify in the coming days.

Cumulonimbus clouds are expected to increase daily during the afternoon and evening hours over the far southwestern highlands of the Kingdom, including the highlands of Jazan, Asir, and Al-Baha, with the possibility of them extending to parts of the highlands of Makkah Al-Mukarramah, especially the city of Taif. These clouds are accompanied by thunderstorms that may be locally heavy, especially over the highlands of Jazan and Asir, where strong thunderstorms and heavy hail are likely.

In a related context, weather indicators indicate the possibility of humid tropical currents extending their influence towards southern Egypt during the first days of August, particularly in the mountainous highlands of the Red Sea Governorate. This could lead to the formation of scattered thunderstorms in these areas.

What is orbital separation?

The Intertropical Zone (ITCZ) is a climate zone created by the convergence of northeasterly trade winds from the Northern Hemisphere and southeasterly trade winds from the Southern Hemisphere. This convergence causes air to rise, causing cloud formation and heavy rainfall.

How does the tropical break affect the Arab world in the summer?

The tropical break primarily affects southern regions such as Sudan, Yemen, and parts of Saudi Arabia. During the summer, the tropical break moves north, bringing seasonal rains to these areas. This can lead to heavy rainfall and occasional flooding.

And God knows best.
