Life-Threatening Heat Domes Are Confounding Forecasters

Life-Threatening Heat Domes Are Confounding Forecasters

Bloomberg10-07-2025
Record-breaking temperatures seared the eastern US last month, leading to power emergencies across the region. The cause: an enormous ridge of high pressure that settled on the region, known as a heat dome.
This phenomenon has also already struck Europe and China this summer, leading to the temporary closure of the Eiffel Tower and worries about wilting rice crops, respectively. But while heat domes are easy to identify once they strike, they remain difficult to forecast — a problematic prospect in a warming world.

Heavy rains in northern China kill 4 as Beijing and nearby areas brace for more

Heavy rains in northern China kill 4 as Beijing and nearby areas brace for more TAISHITUN, China (AP) — Heavy rain and flooding in northern China killed at least four people and left several others missing Monday as tens of thousands of people were evacuated from areas around Beijing where more downpours were forecast. The four victims were caught in a landslide in a rural part of Luanping county in Hebei province near the capital, state broadcaster CCTV reported. Eight people were missing. A resident told the state-backed Beijing News that communications were down and he couldn't reach his relatives. More than 40,000 people were evacuated from outer districts of Beijing and the neighboring city of Tianjin as authorities released water from a reservoir in Beijing's rural Miyun district that was at its highest level since it was built in 1959. Authorities warned people to stay away from rivers downstream as their levels rose and as more heavy rain was forecast. Heavy flooding washed away cars and downed power poles in Miyun district, which borders Luanping county. China's Premier Li Qiang said Monday that the heavy rain and flooding in Miyun caused 'serious casualties,' and called for rescue efforts, according to China's Xinhua News Agency. Uprooted trees lay in piles with their bare roots exposed in the town of Taishitun, about 100 kilometers (60 miles) northeast of central Beijing. Streets were covered with water, with mud left higher up on the wall. 'The flood came rushing in, just like that, so fast and suddenly. In no time at all, the place was filling up,' said Zhuang Zhelin, who was clearing mud with his family from their building materials shop. Next door, Zhuang's neighbor Wei Zhengming, a traditional Chinese medicine practitioner, was shoveling mud in his clinic; his feet in slippers were covered in mud. 'It was all water, front and back. I didn't want to do anything. I just ran upstairs and waited for rescue. I remember thinking, if no one came to get us, we'd be in real trouble,' said Wei. Beijing authorities launched a top-level emergency response at 8 p.m. Monday, ordering people to stay inside, closing schools, suspending construction work and stopping outdoor tourism and other activities until the response is lifted. The heaviest rain in Beijing was expected early Tuesday, with rainfall of up to 30 centimeters (12 inches) forecast for some areas. CCTV reported that more than 30,000 people were evacuated from Beijing districts, including about 6,400 from Miyun where the reservoir is located. Another 10,000 people were evacuated from the nearby Jizhou district under the city of Tianjin, Xinhua reported. The central government said in a statement it had sent 50 million yuan (about $7 million) to Hebei and dispatched a high-level team of emergency responders to help the affected cities, which include Chengde, Baoding and Zhangjiakou. Beijing and Hebei suffered severe flooding in 2023. ___ Moritsugu reported from Beijing.

Heat dome continues to raise temps across South and Midwest, will begin to move into Northeast

'Corn sweat' has increased temperatures throughout the Plains and Midwest this week. The 'heat dome' that has hovered over tens of millions of people in the South and Midwest this week is now spreading into parts of the Northeast on Thursday, according to the Weather Channel. A heat dome is a high-pressure bubble in the upper levels of the atmosphere that traps hot air and sun radiation underneath it. The Climate Reality Project, a nonprofit focused on climate change advocacy and education, compares heat domes to putting a lid on a hot pot; the lid keeps the hot air from leaving the pot and keeps the contents of the pot hot for a longer time. While late July usually is the hottest time of the year for most of the U.S., AccuWeather reports these temperatures will be 5 to 15 degrees Fahrenheit higher than the historical average. An 'Extreme Heat Watch' advisory alert, which warns 'dangerous heat is possible,' was issued for West Virginia on Thursday. An 'Extreme Heat Warning' alert, which warns 'dangerous heat is happening or about to happen,' was sent to areas in Illinois, Missouri, Mississippi, Arkansas, Louisiana, Kentucky, Tennessee, New Jersey, Delaware, Pennsylvania and New York on Wednesday. Some of these extreme heat warnings were sent to major cities like Boston, Detroit, New York City and Washington, D.C., where temperatures will reach the mid-90s by Friday, the Weather Channel reported. However, temperatures in these areas are expected to drop over the weekend. Parts of the Midwest and the South will still be in temperatures near or above 100 degrees through the rest of the weekend, and potentially into the middle of next week. Florida, which has been experiencing hot and muggy conditions across the state all week, will continue to experience high temperatures in the upper 80s to lower 90s on Thursday and Friday, according to Florida Disaster, a division of the state's Department of Emergency Management. The state's heat index values will be particularly high on the western side of the Florida Panhandle, compared to the rest of the state. (The National Weather Service (NWS) 'heat index' is a calculator that estimates what outdoor temperatures feel like to the human body.) Experts cannot determine exactly when the heat dome will end. Heat domes take a long time to break down, Bryan Jackson, a meteorologist at the NWS's Weather Prediction Center, told Scientific American, so the extreme heat is expected to last through the rest of the week for some areas. 'Corn sweat' drives up humidity in the Midwest As heat index values in the Midwest peaked this week because of the heat dome, high humidity levels have contributed to 'corn sweat' in these areas. Corn sweat is a colloquial nickname for evapotranspiration, which is when plants, like corn stalks, release water vapor into the air and essentially turn it into additional humidity that can drive up humidity levels and heat index numbers in the area, according to the Weather Channel. This mostly affects people in the Midwest, with residents in Missouri, Indiana, Iowa, Illinois and Kentucky experiencing heat index numbers in triple-digits because of the corn sweat, the Washington Post reported. The corn sweat has also affected these areas' dew points, which correlate to how much moisture is in the air, NWS explains. The higher the dew point, the more muggy and wet the air will feel. A dew point minimum of 75 equates to an extreme humidity level and feels 'oppressive, like a tropical rainforest,' according to the Washington Post. In areas affected by the corn sweat, such as southern Missouri, the dew point is at 88. Northeast, Midwest also warned about severe thunderstorms AccuWeather meteorologists alerted on Wednesday that severe thunderstorms are expected to move across the Midwest before hitting the Northeast in the next few days. These storms carry the potential for high winds and hail, according to AccuWeather meteorologists. The worst of the storms are expected to hit throughout Thursday afternoon and evening, mostly affecting cities like Chicago, Detroit, Oklahoma City and Kansas City, before shifting into the Northeast on Friday. While it's rare to see precipitation happen within a heat dome, severe thunderstorms are likely to form around its edges, often called the 'ring of fire.' "In the world of meteorology, the ring of fire deals with thunderstorms along the northern edges of strong upper-levels high,' AccuWeather meteorologist Bernie Rayno said. 'Oftentimes, this setup produces severe thunderstorms along the northern edges of the heat.' How to stay safe in extreme heat Extreme heat is the deadliest type of weather in the U.S., even more so than tornadoes, flooding or hurricanes, according to research by the NWS. Prolonged extreme heat, as is expected in the heat dome this week, is especially dangerous for people who do not have access to air-conditioning or who spend a lot of time outdoors. If you live in a place that will be affected by the heat dome, here's what to do to help protect yourself: Stay indoors and cool for as long as you can. Here is a list of public places you can go to for free air-conditioning. Stay hydrated. Adding electrolytes to your drinking water can further protect you from dehydration. If you need to go outside, protect your skin by wearing sunscreen with an SPF of 30 or higher, sun-protective clothing and UV-blocking sunglasses. Understand and look out for symptoms of heat-related illness. These include heavy sweating, fatigue, dizziness, muscle cramps, nausea and headaches. If you are experiencing these symptoms, move to a cool area to rest and hydrate. Solve the daily Crossword
