What is a heat dome?

According to Texas climatologist John Nielsen Gammon, the heat dome is created when a stationary anticyclone with warm air combines with warmer-than-usual air over the Gulf of Mexico and heat from the sun nearly overhead.

“By the height of summer, it becomes harder for hot air to rise,” says Nielsen Gammon, a professor at Texas A&M College of Atmospheric Sciences. “If that happens, now is the time of the year.”

Nielsen Gammon said July and August don’t get as much sunlight because the sun is receding from the sun. summer solsticeit was Wednesday.

“What’s a little different about this heat wave is that April and May were pretty wet, and that extra humidity usually acts as an air conditioner,” said Nielsen-Gammon. rice field. “But the air up there is so hot that it didn’t prevent a heat wave from happening, and it actually made it a little bit more humid.”

The heat wave continues this week, with the Texas Power Reliability Council, the Texas power grid operator, being affected by the heat wave. I asked a resident last week Due to the expected record demand on the system, we need to voluntarily reduce our power usage.

Symptoms of heat stroke include profuse sweating, nausea, dizziness, and fainting. Ways to stay cool include drinking cold drinks, applying cold water soaked cloths to your skin, and spending time in air-conditioned environments.

Cecilia Sorensen, a physician and associate professor of environmental health sciences at Columbia University Medical Center, said heat-related symptoms are a growing public health concern due to a warming climate.

“Texas is currently in big trouble around energy insecurity and a worsening climate crisis,” Sorensen said. “This is also one example of how if you are wealthy enough to buy air conditioning, you are safer. This is a big issue for health equity on climate change.”

Since 1993, average daily high temperatures in Texas have increased 2.4 degrees Celsius, or 0.8 degrees Celsius per decade. according data The announcement from the National Oceanic and Atmospheric Administration amid concerns about man-made climate change causing rising temperatures.
