Heat waves form when high pressure air settles high in the air and causes hot air to sink down. The hot air sinking creates a bubble that acts like a seal and traps heat near the ground. This seal keeps out convection currents that form clouds and eventually rain clouds, both of which would help the area affected cool off.
First, the jet stream must be positioned across northern states/Canada border or even farther north. This allows high pressure to develop, thus creating sunny, dry weather. As the high pressure stays over a certain area, it strengthens and the pressure (measured in millibars) gets higher and higher. Thus creating air that gets hotter and hotter.
A common query we ran across in our research was “What determines a heat wave?”.
A heat wave is an extended period of abnormally high temperatures experienced within a specific region. Conditions are officially declared a heat wave when the daily maximum temperature is at least 5° Celsius (9° Fahrenheit) warmer than the average maximum temperature for 5 consecutive days or more.
How do you survive a heat wave?
Typical heat waves have already become more frequent and sustained here he said. The trees have to survive and grow for them to provide the desired benefits. “A lot of funders get very excited when we can come back and say we’ve successfully.
There’s a heat wave in town—here are 8 ways to cool down. Use fans and air conditioning to cool down your house. An air conditioner can bring the temperature way down in your home. Bring down your home’s dew point with a dehumidifier. Humid air can make a home feel much warmer than it actually is. Park yourself in the shade, chill out with cold water, or stay hydrated—it’s essential to staying cool in addition are a couple more items to look into.
