This Tuesday, maximum heat peak with Saharan dust. This morning, I have portrayed for Las Fotos de los Lectores de La Vanguardia the powerful sunrise of a wave of high temperatures photographed from within the water, the sunrise on Gavà beach with a hazy sky.
A lot of caution, especially children and the elderly. Days to drink a lot of water and shelter from the sun. In addition, it must be taken into account that the immediate effect produced by the haze, always depending on its density, is a decrease in visibility, as well as a slight discomfort in the eyes, nose and throat.
The haze is a meteorological phenomenon that consists of the presence in the atmosphere of small particles of dust, ash, clay or sand in suspension.
There are two different types of haze. The first, known as type A, occurs when the suspended particles are dust, salts such as sodium or elements of the environment. Type B is produced by special events, such as forest fires or other polluting events.
The disappearance of the haze is conditioned by changes in atmospheric pressure, which can give rise to wind or rain.
A continued exposure in a haze can cause other more serious symptoms. Bronchospasm, which makes it difficult to breathe and respiratory crises can appear as a consequence of the haze.
In addition, it is advisable not to expose yourself and protect yourself from the haze if you have respiratory problems such as asthma or even allergies.
Another phenomenon that is observed is that of the many sunspots. It seems that they are going further. Let's see what the scientists say.
A sunspot is a region of the sun that has a lower temperature than its surroundings and with intense magnetic activity. It consists of a dark central region, called the "umbra," surrounded by a lighter "penumbra."
A single spot can measure up to 12,000 km (almost as large as the diameter of the Earth), but a group of spots can reach 120,000 km in size or more.
