Egypt | How the tropical dividing line transformed the south of the country into a fertile area for thunderstorm activity in the driest months

Arabia Weather - Over recent years, southern Egypt has witnessed noticeable climatic shifts that have greatly affected the precipitation pattern and made the region a fertile field for thunderstorm activity, even in the driest months. This shift is linked to the intertropical separator, which plays a pivotal role in weather changes in the region.

The orbital separator and its role in weather

The Intertropical Separator (ITCZ) is an area of low pressure located near the equator, where trade winds from the northern and southern hemispheres meet. This region is characterized by intense thunderstorm activity due to the rise of hot, humid air and the formation of dense clouds. As the tropical dividing line moves north during the summer, southern Egypt comes within its sphere of influence, leading to an increase in thunderstorm activity.

The effect of the tropical separator on southern Egypt

Increased atmospheric humidity: As the tropical dividing line moves north, it brings large amounts of moisture from the Atlantic and Indian Oceans. This increase in humidity provides the fuel needed for thunderstorms to form.

High temperatures: High temperatures in southern Egypt lead to heating of the air, which contributes to increased atmospheric instability. When hot air meets moist air coming from the intertropical separator, intense thunderstorm activity forms.

Monsoon winds: Monsoon winds coming from the Indian Ocean contribute to enhancing the effect of the tropical break, bringing more moisture and enhancing the chance of thunderstorms.

Climatic shifts and the impact of the tropical break on southern Egypt are a vivid example of how climate changes affect local weather patterns. Understanding these phenomena helps develop strategies to adapt to climate change and reduce its negative impacts on the environment and local communities.

God knows.
