Wind is a mass of air with a certain direction, speed and intensity. This action of nature is highly variable, since it can generate from a light breeze to a gale or a hurricane. It can be said that each type of wind has its own history
Characteristics of the zonda wind
This name is used in the western territory of Argentina, specifically in the vicinity of the Andes Mountains.
Its origin is found in the anticyclones that occur in the Pacific Ocean and that finally move in the form of cold air currents towards the Andes Mountains. Its main characteristics are the following: it is extremely strong and dry and has high temperatures.
When it descends it loses its humidity and for this reason it becomes dry and warm. In this way, the Zonda wind in flat places causes the dragging of dust during the Argentine winter.
Its force has been described as a descending jet and its greatest intensity occurs during the afternoon, since at these times of the day there is normally an increase in temperature. When the force of this wind stops for a few hours or days, they speak of the "pause of the Zonda".
Main effects on populations and the environment
In populated territories, the gusts of this wind cause significant damage: roof blasting, interruption of electrical services or activation of fires.
At the same time, its strength affects agriculture, since the dryness of the Zonda alters the production of some fruits. Its continued presence affects the evaporation of snow in high mountain areas and this circumstance causes avalanches and rock falls.
It also affects health
The weather in general and the wind in particular have direct effects on health. In the case of the Zonda wind, its impact on various aspects of health has been studied.
It affects mood and can trigger some forms of depression. It exacerbates chronic pain, especially in those who have migraine.
People with mental disorders have been found to be very sensitive to the action of the wind. The zonda wind is related to aggressiveness and irritability.
Other winds with similar characteristics, for example all those that occur in desert territories, have very similar effects on health. The medical discipline that studies the relationships between climate and health is biometeorology.
