Heat Dome
A heat dome is caused when atmosphere traps hot ocean air, as if bounded by a lid or cap. The upper air weather patterns are slow to move, referred to by meteorologists as an Omega block. Creation of heat domes In still, dry summer conditions, a mass of warm air builds up. The high pressure from the Earth's atmosphere pushes the warm air down. The air is compressed, and as its net heat is now in a smaller volume, so it must get hotter. As the warm air attempts to rise, the high pressure above it forces it down, to get hotter, and its pressure grows higher. The high pressure acts as a dome, causing everything below it to get hotter and hotter. The term is often extrapolated in the media terminology for any heat wave situation. The term heat dome is also used in the context of urban heat islands.

Heat Wave
A heat wave, or heatwave, is a period of excessively hot weather, which may be accompanied by high humidity, especially in oceanic climate countries. While definitions vary, a heat wave is usually measured relative to the usual climate in the area and relative to normal temperatures for the season. Temperatures that people from a hotter climate consider normal can be called a heat wave in a cooler area if they are outside the normal climate pattern for that area. The term is applied both to hot weather variations and to extraordinary spells of hot weather which may occur only once a century. Severe heat waves have caused catastrophic crop failures, thousands of deaths from hyperthermia, increased risk of wildfires in areas with drought, and widespread power outages due to increased use of air conditioning. A heat wave is considered extreme weather, and poses danger to human health because heat and sunlight overwhelm the human body's cooling system. Heat waves can usually be ...

Dome
A dome () is an architectural element similar to the hollow upper half of a sphere. There is significant overlap with the term cupola, which may also refer to a dome or a structure on top of a dome. The precise definition of a dome has been a matter of controversy and there are a wide variety of forms and specialized terms to describe them. A dome can rest directly upon a rotunda wall, a drum, or a system of squinches or pendentives used to accommodate the transition in shape from a rectangular or square space to the round or polygonal base of the dome. The dome's apex may be closed or may be open in the form of an oculus, which may itself be covered with a roof lantern and cupola. Domes have a long architectural lineage that extends back into prehistory. Domes were built in ancient Mesopotamia, and they have been found in Persian, Hellenistic, Roman, and Chinese architecture in the ancient world, as well as among a number of indigenous building traditions throughout t ...

2021 Western North America Heat Wave
The 2021 Western North America heat wave was an extreme heat wave that affected much of Western North America from late June through mid-July 2021. Rapid attribution analysis found this was a 1000-year weather event, made 150 times more likely by climate change. The heat wave affected Northern California, Idaho, Western Nevada, Oregon, and Washington in the United States, as well as British Columbia, and in its latter phase, Alberta, Manitoba, the Northwest Territories, Saskatchewan, and Yukon, all in Canada. It also affected inland regions of Central and Southern California, Northwestern and Southern Nevada and parts of Montana, though the temperature anomalies were not as extreme as in the regions farther north. The heat wave appeared due to an exceptionally strong ridge centered over the area, whose strength was linked to the effects of climate change. It resulted in some of the highest temperatures ever recorded in the region, including the highest temperature ever mea ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
2021 British Columbia Wildfires
The 2021 British Columbia wildfires burned across the Canadian province of British Columbia. The severity of the 2021 wildfire season is believed to have been caused by a "perfect storm" of environmental factors exacerbated by human-caused climate change. As of August 16, over 1,500 fires had been recorded according to the BC Wildfire Service. The Sparks Lake Fire was the largest fire burning in the province, having burned an estimated 95,980 hectares (237,172 acres) of the Bonaparte Plateau northwest of the city of Kamloops. Development A heat dome gripped the province of British Columbia, and much of Western North America, from June 25–30, 2021, increasing the risk of wildfires. On June 30, the town of Lytton was evacuated due to a fire that destroyed most buildings and grew to over and sent people fleeing for their lives. By July 1, 2021, almost 500 wildfires were burning across British Columbia. On July 20 the B.C. government declared a state of emergency. Wildfir ...

2018 North American Heat Wave
The 2018 North American heat wave affected regions of Canada, where at least 70 deaths in Quebec were heat-related, the United States, where 18 states between Michigan and New Mexico issued heat advisories to a population of over 60 million people, and of Mexico, particularly the northwest and central regions. Canada Quebec and Ontario From June 29 to July 6, 2018, the air temperature consistently rose above in parts of Quebec and Ontario. The humidex value for Ottawa on Canada Day between noon and 3 pm was , the highest ever recorded in the city. The humidex also peaked at in Toronto and in Montreal. The heat wave also affected the Maritimes, with the humidex value reaching in Halifax and at Greenwood in the Annapolis Valley, on 5 July. On 4 July, Montreal emergency services reported twelve hundred calls per day about the heat, up 30% from prior busiest days. As of 10 July, seventy-four people, most of them already ill, had died heat-related deaths in Quebec. Thi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
2012 North American Heat Wave
The Summer 2012 North American heat wave was one of the most severe heat waves in modern North American history. It resulted in more than 82 heat-related deaths across the United States and Canada, and an additional twenty-two people died in the resultant June 2012 North American derecho. This long-lived, straight-line wind and its thunderstorms cut electrical power to 3.7 million customers. Over 500,000 were still without power on July 6, as the heat wave continued. Temperatures generally decreased somewhat the week of July 9 in the east, but the high pressure shifted to the west, causing the core of the hot weather to build in the Mountain States and the Southwestern United States shifting eastwards again by mid-July. By early August, the core of the heat remained over the Southern Plains. Cause The heat wave formed when high pressure aloft over the Baja California, Mexico, strengthened and moved over the southern plains around June 20–23 and then spread east and northwa ...

Atmosphere Of Earth
The atmosphere of Earth is the layer of gases, known collectively as air, retained by Earth's gravity that surrounds the planet and forms its planetary atmosphere. The atmosphere of Earth protects life on Earth by creating pressure allowing for liquid water to exist on the Earth's surface, absorbing ultraviolet solar radiation, warming the surface through heat retention (greenhouse effect), and reducing temperature extremes between day and night (the diurnal temperature variation). By mole fraction (i.e., by number of molecules), dry air contains 78.08% nitrogen, 20.95% oxygen, 0.93% argon, 0.04% carbon dioxide, and small amounts of other gases. Air also contains a variable amount of water vapor, on average around 1% at sea level, and 0.4% over the entire atmosphere. Air composition, temperature, and atmospheric pressure vary with altitude. Within the atmosphere, air suitable for use in photosynthesis by terrestrial plants and breathing of terrestrial animals is found ...

Atmospheric Pressure
Atmospheric pressure, also known as barometric pressure (after the barometer), is the pressure within the atmosphere of Earth. The standard atmosphere (symbol: atm) is a unit of pressure defined as , which is equivalent to 1013.25 millibars, 760mm Hg, 29.9212 inchesHg, or 14.696 psi.International Civil Aviation Organization. ''Manual of the ICAO Standard Atmosphere'', Doc 7488-CD, Third Edition, 1993. . The atm unit is roughly equivalent to the mean sea-level atmospheric pressure on Earth; that is, the Earth's atmospheric pressure at sea level is approximately 1 atm. In most circumstances, atmospheric pressure is closely approximated by the hydrostatic pressure caused by the weight of air above the measurement point. As elevation increases, there is less overlying atmospheric mass, so atmospheric pressure decreases with increasing elevation. Because the atmosphere is thin relative to the Earth's radius—especially the dense atmospheric layer at low altitudes—the Earth's ...
