According to SciTech Daily, a phenomenon called the "atherve" has created the premise for significantly high temperatures as the summer of meteorology is taking place.
As the meteorological summer has just begun, some areas in the Northern Hemisphere have felt the heat in early June 2021. In particular, the heat at the beginning of the season has burned countries across the Middle East, the US and Europe.
The map below shows the air temperature in the Middle East on June 6, 2021. The map is taken from the Goddard Earth observation system (GEOS) model and describes air temperatures at an altitude of 2 meters above ground. The areas with the darkest red color are where the model shows temperatures around 50 degrees Celsius.
The GEOS model, like all weather and climate models, uses toanistic equations that represent physical processes (such as rain and clouds) to calculate how the atmosphere will function. field measurements of physical properties, such as temperature, humidity, and wind, are often included in models to keep the simulation as close to observed reality as possible.
Local ground stations have recorded temperatures climbing above 50 degrees Celsius in at least four Middle Eastern countries, including Iran, Kuwait, Oman and the United Arab Emirates (UAE).
According to weather forecasts, Sweihan in the UAE reached 51.8 degrees Celsius on June 6, the highest temperature recorded in June in the country. Countries in Central and South Asia were also reported to have seen unusually high temperatures during the year.
Meteorologists at The Washington Post report that heat waves are the result of a " thermal dome". This phenomenon occurs when high pressure in the mid to upper atmosphere acts as a lid, keeping the hot air as it flies up and pushing it back to the surface to get hotter.
A notable phenomenon has occurred, causing temperatures across the Middle East to spike in July and August 2015. This year's heat wave comes about a month before the hottest temperature of summer typically arrives.
Also in June, the US and Europe are experiencing a record heat wave. As of June 17, the heat wave in most of the western United States has entered its third day with record-high temperatures, such as Salt Lake in Utah, as measured on June 15 at 42 degrees Celsius.
Meteorologists say the unusual heat wave in the US in late spring was due to high pressure forming in the southwestern deserts.
Meanwhile, many European countries have also seen temperatures increase to record levels since 2019 this week.
The ASEAN Climate perspective Forum (ASEANCOF) has issued a seasonal forecast for Southeast Asia from June to August 2021. Above-average temperatures are forecast for Southeast Asia during this period. Areas with the highest possibility of above normal temperatures include Central Myanmar, Malaysia, Singapore and Central and South Vietnam.
In Vietnam, the heat wave occurring in the North and Central regions is also considered one of the most severe heat waves of 2021. Due to the influence of the hot low pressure area in the west combined with the flattening effect, the North and Central regions will have severe heat, some places are especially harsh with the highest temperature commonly 36-39 degrees Celsius, some places above 40 degrees Celsius on June 18.
According to the National Center for Hydro-Meteorological Forecasting, hot weather in the Northern region and the Central provinces will appear frequently from now until August. In the North, the heat is strong and severe concentrated in the months of June and July, the Central region, the heat is hot and the heat can continue into August.
