HEAT WAVES

What Causes A Heat Wave?

the Bible states about a hot wind from the bare height in the desert :

Jeremiah 4:11 “At that time it will be said to this people and to Jerusalem, “A hot wind from the bare heights in the desert toward the daughter of my people, not to winnow or cleanse.”

A heatwave occurs when a system of high atmospheric pressure moves into an area and lasts two or more days. In such a high-pressure system, air from upper levels of our atmosphere is pulled toward the ground, where it becomes compressed and increases in temperature.

This high concentration of pressure makes it difficult for other weather systems to move into the area, which is why a heatwave can last for several days or weeks. The longer the system stays in an area, the hotter the area becomes. The high-pressure inhibits winds, making them faint-to-nonexistent. Because the high-pressure system also prevents clouds from entering the region, sunlight can become punishing, heating up the system even more. The combination of all of these factors come together to create the exceptionally hot temperatures we call a heatwave.

Heat Waves Can Be Deadly

While the phrase “dangerous weather” may conjure up images of blizzards, hurricanes or tornadoes, it’s important to remember that heatwaves can be deadly. During a heatwave, you can protect yourself by staying out of the sun during the hottest parts of the day, avoiding strenuous activities, and keeping yourself hydrated with plenty of fresh water.

And when humidity and dew points are high along with the temperatures, things can get very uncomfortable!
