Heat wave is an unusually hot weather phenomenon in which a certain area has high temperatures and high humidity that can last for several days. During this period, the normal temperatures of the area are many times higher than the usual temperatures of the corresponding season. The heat wave poses a number of threats to the inhabitants of a particular area and, if prolonged, can lead to many deaths and serious illnesses. The heat wave can be relatively dependent on where you live. For some, certain normal temperatures can be viewed as a heat wave for a person coming from a low temperature range.
What causes a heat wave?
A heat wave occurs when the upper atmosphere contains high pressure which makes it stationary in an area. This stationary air mass can stand for days and weeks, retaining more heat and reducing convection currents. As a result, heat and high humidity are accumulated without any precipitation or precipitation. This creates unusually high temperatures. Heat waves are quite common in the northern hemisphere during the summer season from May to November.
The high pressure forces the air to sink to the surface of the land and acts as a barrier to heat rise. This will cover the surface of the earth and record all weather conditions without them being able to escape.
Dangers of heat
The heat wave is potentially more dangerous than other natural events such as hurricanes, lightning and tornadoes. In addition to uncomfortably high temperatures, heat waves can lead to heat problems, poor air quality, forest fires and drought.
The probability of a heat wave is very high due to global warming and climate change. Because global warming is destroying the ozone layer, which prevents harmful sun rays from reaching the earth’s surface. This increases the global average temperature and thus the starting point of the heat wave.
