What is dry lightning?

dry lightning is lighting that hits without any accompanying rain. Obviously, the "dry" flash is a little redundant, because lightning is not usually particularly wet, but the term has caught because it is so descriptive. The Western region of the United States is known for its dry flash, which sparks hundreds of fires every year, some of which are dangerously large. When the flash hits the ground, it can cause a flame spark, but the rain that descends with the flash will pull out the fire before having a chance to spread. Rain is produced in a dry storm, but never reaches the ground. Dry, warm air causes the rain to evaporate and return Semrak and drive the storm, while ensuring that it does not interfere with the ground to fire fires caused by lightning strikes. Such storms are also often accompanied by dry microbursts, cold air gusts that rush down from the clouds and spread quickly as they hit the ground, causing winds along the surface of the ground.

As one can imagine, dry flashes and dry microburste can be a recipe for a disaster. Even if the lightning hit the soil to cause fire, the gust of wind can push the edges of the fire, causing it to spread rapidly. In areas where ground and forests are not well managed, explosive fire conditions may appear during the storms in Suchý Blesk, quickly cover the soil and sometimes even capture fire staff.

In general, the risk of dry flash can be predicted in advance, with meteorologists using existing data to predict dry demolition. In these cases, a warning may be issued that warn people of the risk of fire, and the risk of unpredictable storms leads to many communities to encourage citizens to create a fireplace in their homes by maintaining the ground cover and tightly cutting grass. In areas where there is particularly common dry flashes, building regulations may also include built -in fire protection to make fires less likely to structureDOVNÁ.
