How it comes to the heat wave – and how long it takes this time – know

If you go after the start of the calendar, summer just started, on June 21st. Furthermore, But shortly afterwards there were temperatures of more than 35 degrees Celsius in some places. Nevertheless, and now the first strong heat wave is imminent: Already on Tuesday it should be up to 38 degrees, especially in the middle of Germany and in the southwest. Moreover, On Wednesday. In addition, the heat records almost all of Germany, in some places it could get almost 40 degrees, according to the German Weather Service (DWD).

The high at the weekend Anita the temperatures are driven up. Therefore, It was the end of a so -called high -pressure bridge. Moreover, a connection between two high -pressure areas that ranged from the central North Atlantic to Germany. Furthermore, It brought warm air, especially how it comes heat wave in the south. In the night of Monday it was again cool in the north after a cold front passage, with single-digit temperatures. But followed up high Bettinathat headed east on Monday or moved.

Germany is now on its back. Since high in the northern hemisphere rotated clockwise, they pull warm air from the south, i.e. on their western edge. In this case, she comes from north africa in a well -preserved manner, and the heat wave can begin. The heat is reinforced by the almost unhindered sunlight: the sky should remain largely clear consistently. so that more than 15 hours of sun will come together, especially on Tuesday and the air continues to heat up. In addition, drought can occur: In June it rained too little. If the floor is very dry, hardly any water can evaporate and thus alleviate the heat.

On Thursday it how it comes heat wave should be cooler at least in the north

It doesn’t necessarily get better at night. In the night of Wednesday. there should be “tropical nights” in the west of Germany in many places in which the temperature does not fall below 20 degrees. In the night of Thursday, this applies to a wide strip from the southwest to the northeast. Such nights used to be the absolute exception. In the comparison period from 1961 to 1990. most of the DWD measurement stations were not even one year on average, according to DWD 3.3 in the warm Heidelberg. But such nights become more common with increasing temperatures: Already in the comparison period 1981 to 2010 there were 4.5 in Heidelberg, in extreme summer such as 2003 or 2018 there were more than eight tropical nights in some places.

“Heat waves already existed in the past, but we observe that they appear frequently and with increasing intensity,” says DWD meteorologist Nico Bauer. New all-time records are currently not expected, but there can be new ward records at individual stations. The previous temperature record for Germany is 41.2 degrees Celsius, measured in July 2019; This value should not be reached again for the time being.

After all, the current heat wave will probably not be long -lasting. It should be cooler again in the north on Thursday. and on Friday only 23 to almost 30 degrees are expected across Germany.
