A phenomenon known as a “heat dome” set the stage for remarkably high temperatures as meteorological summer got under way.
With meteorological summer just underway, some parts of the Northern Hemisphere were already feeling the heat in early June 2021. In particular, the early-season heat has been scorching countries across the Middle East.
The map above shows air temperatures in the region on June 6, 2021. The map was derived from the Goddard Earth Observing System (GEOS) model and depicts air temperatures at 2 meters (about 6.5 feet) above the ground. The darkest red areas are where the model shows temperatures around 50°C (122°F).
The GEOS model, like all weather and climate models, uses mathematical equations that represent physical processes (such as precipitation and cloud processes) to calculate what the atmosphere will do. Actual measurements of physical properties, like temperature, moisture, and winds, are routinely folded into the model to keep the simulation as close to observed reality as possible.
Indeed, local ground stations recorded temperatures that climbed above the 50°C mark in at least four Middle Eastern countries, including Iran, Kuwait, Oman, and the United Arab Emirates (UAE). According to news reports, Sweihan in the UAE hit 51.8°C (125.2°F) on June 6, 2021, which was the country’s highest temperature on record for the month of June. Countries in Central and South Asia were also reported to have seen extraordinarily high temperatures for the time of year.
Meteorologists at The Washington Post reported that the heatwave is the result of a “heat dome.” The phenomenon occurs when high pressure in the mid- to upper-atmosphere acts as a cap, trapping warm air as it rises and pushing it back toward the surface to warm even more. A notable occurrence of the phenomenon caused temperatures to soar across the Middle East in July and August 2015. The heatwave this year comes about a month before the hottest temperatures of the season typically arrive.

Us Scientists have solutions to recharge the surface of the Drought Sections of the Earth, but we get nowhere when it falls on deaf ears. 100% do we have options to pull California out of the Drought Water Crisis. Email us Scientists and more so myself and we Scientists can prove it can be done to start to turn the Drought Nations Wet Again. Scitechdaily you email me only not the general public please, and I will show you the proven Technologies to shift this Drought around. It’s going to take some time but it can be done. People just call me “Doc Hansen”
