is that these types of events will become increasingly frequent
Since the end of May the meteorology in Spain has been A roller mountain in which summer heat days have alternated with days of thermal drops and abundant storms. And if the last of these episodes of instability has been characterized by something has been for the intense hails seen in some points of the peninsular center. After the beak. After reaching Wednesday its peak of activity, the last stormy episode begins to love the Peninsula. However, the chronicle of a hail leaves us that in some places reached the ground with a considerable size such as three centimeter balls Views in Madrid. And suddenly, Pedrisco. The big question is how we have come to see such a situation in the middle of June, when the weather spring has come to an end. The key may be precisely in the thermal oscillations that we have lived during these weeks. According to they explain from Eltiempo.essurface heat generates ascending convective currents. These are entered into clouds of great vertical growth and raise water drops to large heights. From water to ice. These drops, in their ascent they can reach very cold layers of the atmosphere, when reaching the -15º Celsius They begin to form hail. Ice falls by gravity, but can rise again trapped by convective currents. When descending, hail captures moisture dragged by the warm air that returns it to the high and cold layers. The result is hail balls that increasingly accumulate more water, more mass and greater diameter. Finally, atmospheric instability ends up unleashing storms in which accumulated hail is precipitated against the surface. End of the stormy episode. Meteorologists point out that the last stormy episode has come to an end: the Dana responsible for instability seen these days moves away from the peninsula. However, storms will not complete has issued several notices For storms and possibility of hail. Among these notices are orange notices due to an important risk of storms, in force tomorrow on the Ebro banks in Zaragoza and in the province of Huesca. In some areas, storm notices of these days will coexist with notices due to high temperatures. A problem that will go to more. Climate experts point out that the frequency and intensity of extreme weather phenomena will increase as a consequence of climate change. Although we associate storms to instability and cold, heat plays an important role. The heat not only generates ascending currents that alter the structure of the clouds, there is also the fact that hot air causes the atmosphere to accumulate more moisture. More water in the atmosphere means greater rainfall associated with storms such as those lived during these days.
