A heat wave or heatwave, sometimes described as extreme heat, is a period of abnormally hot weather [1]: 2911 generally considered to be at least five consecutive days. A heat wave is usually measured relative to the usual climate in the area and to normal temperatures for the season. [2]
The term 'heat dome' has gained prominence recently as climate change, El Niño and other variables have warmed global temperatures and shifted weather patterns. Heat wave or heat dome? Yes, there ...
The worst heat wave in the US occurred in 1936 and killed more than 5000 people directly. The worst heat wave in Australia occurred in 1938–39 and killed 438. The second worst was in 1896. Power outages can also occur within areas experiencing heat waves due to the increased demand for electricity (i.e. air conditioning use). [15]
"The 'heat wave' definition varies on where you are," DeSilva said. "But across the mid-Atlantic region, a heat wave is any three-day stretch of 90-degree weather or hotter.
June 29, 2017, Greece heat wave - hot air mass from Sahara Desert extended to the Balkans resulting in temperatures of 42˚C to 45˚C for three consecutive days. [75] In September 2017 a heat wave affected a large portion of the Eastern United States; it is notable for producing unusually hot temperatures the latest in a calendar year in places ...

For marine heatwave, the teleconnection process that play a dominant role are atmospheric blocking/subsidence, jet-stream position, oceanic kelvin waves, regional wind stress, warm surface air temperature, and seasonal climate oscillations. These processes contribute to regional warming trends that disproportionately effect Western boundary ...
The summer is coming in hot: As Thursday's solstice approaches, a heat wave is hitting the East Coast and Midwest and expected to last through at least Friday.
