The return of Saharan dust
The heat It is still The undisputed protagonist of this summer start, but this week he gives us a brief truce again, at least in the western half of the peninsula. The reason is on the arrival of a Dana from the Atlantic. A Dana that will refresh us but that is also going to collect its price. The calima returns. The calima shape, suspension powder from the Sahara. The forecasts indicate That the arrival of a new isolated depression at high levels, a Dana, will bring more than rains and instability. In this sense, it is expected to be during the day today that the greatest concentrations will be achieved. The arrival of calima fueled by an unstable atmosphere has one more consequence, the “rain of blood” or mud. This phenomenon occurs when the rain drags the dust in suspension, clouding and embarking the surfaces on which water and particles are deposited. According to The forecasts From the State Meteorology Agency (Aemet), the entrance of Calima will occur from Alborán and will reach the Southwest Peninsular, where they could lead to these clay rains. Tomorrow the calima could reach the eastern third of the Peninsula and the Balearic archipelago. A DANA -shaped relief. The good news is that temperatures will fall, first in the western half of the country. Throughout the next few days, meteorologists foresee from a new round of storms, hail and wind. The Dana will also bring instability. Aemet’s forecasts They talk about storms and showers that today can be “locally strong or very strong” and come accompanied by hail and gusts “very strong”, both in the center and in the northern peninsular third. Tomorrow storms and showers could be “locally strong” in addition to coming accompanied by hail and wind in large part of the northwest of the plateau, Cantabrian and Galicia. Given the situation, Aemet will activate today Various yellow and orange notices for rains and storms, especially in the northwestern quadrant of the Peninsula. The orange notices will be activated in much of Castilla y León, as well as in areas of the interior of Cantabria and the Basque Country. Relief, only temporary. The thermal relief propitiated by the Dana will be brief. Experts expect that the second half of the week will bring us back the intense heat of these weeks. Part of the fault will be strengthening A subtropical dorsal that will bring atmospheric stability again in our environment and, with it, will lead to the return of heat. A problem for many. Calima has been a discreet but recurring character in peninsular meteorology, eclipsed by extreme phenomena such as warm episodes and hail storms that we have seen alternate since the end of May. The calima It entails some risks that go beyond the accumulation of dust and mud on the surface. The arrival of dust in suspension can cause irritation in the mucous membranes and obstruct our airways. The result of this can be nasal obstruction, cough or itching in the eyes. Some groups can be specially affected by this atmospheric situation. In Xataka | We do not know anything about El Niño at this point of the year.
