The National Meteorological Service (SMN) reported this forecast on Wednesday strong winds in the northwest and north of Mexico, so they can be tolvanerasAnd meteorological phenomenon also known as A whirlwind of dust or sand.

What are dustbins?

Las tolvaneras hey dust or sand Son weather events This happens when the air close to the ground is very unstable, for example when the ground is very heated by the Sun (insolation).

According to the World Meteorological Organization tolvaneras They are characterized by being a set of dust or sand particles, sometimes with small debris, raised from the ground in the form of a rotating column, of low diameter and whose axis is nearly vertical.

is about dust storm Usually faint, brief, and shallow that can sometimes be seen at the edge of a cumuliform cloud gust front.

This phenomenon occurs as a rotating column of dust that visually resembles a debris cloud from a tornado but without a condensation funnel. Its rotation can be in both directions and occurs around the center.

The vortices are of varying heights, usually 30 meters high, but according to the organization, they have reached a height of one kilometer.

What are the health effects of dust storms?

Omar Amador Muñoz from the Chemical Characterization Laboratory of Atmospheric Organic Aerosols of the National Autonomous University of Mexico (UNAM) assures that tolvaneras has no serious effect on HealthBecause the particles they spread are trapped in the upper respiratory tract because of their size and also because they come from soil.

“Because of their structure, they are water soluble, so they are not bioaccumulative. That is, they dissolve in the body and then are excreted. They do not bioaccumulate like hydrocarbons and do not enter the respiratory system, He clarified.

However, a consequence of tolvaneras is that they can all create poor air quality by dispersing particulate matter.

Recommendations in the presence of dust storms

Despite this, experts and authorities recommend preventive measures such as the use of face mask And preferably not go out, unless absolutely necessary. Apart from avoiding outdoor activities and exercise.
