In major cities, as one approaches tall buildings, they often encounter strong gusts of wind that seem to come from nowhere. These winds not only roar beside the skyscrapers but also often arrive unexpectedly, disregarding the prevailing weather conditions of the day. Sometimes, they come from all directions. Additionally, there are times when the winds blow down from the rooftop to the ground, while at other times, they gust up from the ground to the upper levels.
The reason these winds around tall buildings do not follow a specific pattern mainly lies in the fact that the airflow is disrupted by the tall structures, forcing it to change direction.
Another reason is that air currents with lower speeds, while navigating through the gaps between buildings, experience an increase in velocity.
As a result, the winds emerging from the spaces of towering buildings are always stronger than those in other areas. The strong winds rising from valleys and straits are also attributed to the same causes.
Residents living in southern cities can take advantage of this phenomenon by gathering under tall buildings to enjoy a cool breeze during hot summer nights.
