Thunderstorms irrigate the land of several regions in the African Sahara... How so?

Arab Weather - The regions of southern Libya, southern Algeria and southern Egypt, known as some of the driest regions in the world, are witnessing heavy rains resulting from thunderstorms. These rains are rare in these arid desert regions that fall within the scope of the African Sahara, and come as a result of the influence of the Intertropical Convergence Zone (ITCZ) that moved northward.

Orbital convergence interval and its effect

Arab Weather Center experts said that the intertropical convergence zone is an area of low pressure where trade winds from the northern and southern hemispheres converge. At certain times of the year, the location of this zone is affected by the seasonal movement of the sun, causing it to move north or south. During the summer, the zone moves north, which contributes to increasing the chances of cloud formation and thunderstorms in the desert areas located south of Libya, south of Algeria, and south of Egypt.

The impact of rain on arid areas and will the summer rains continue?

Arab Weather experts pointed out that the sudden rainfall in these arid regions has significant impacts on the local environment. Dry land absorbs water quickly, which can lead to flash floods in some low-lying valleys. However, these rains contribute to reviving temporary vegetation and enhancing groundwater reserves, which benefits local communities that depend on limited water sources.

According to the latest computer modelling, these thunderstorms are expected to continue for several days, with more rain likely in other parts of the Sahara. Although these rains are a blessing in these dry areas, the possibility of flash floods remains a concern for local residents.

The current phenomenon of heavy rainfall in southern Libya, southern Algeria and Egypt highlights the significant impact of the Intertropical Convergence Interval on changing weather patterns even in the driest regions.

God knows best.
