The year 2020 was the warmest since the beginning of the weather records in the observatory on the Hohen Peißenberg in 1781. This is reported by weather observer Siegmar Lorenz in his annual weather review.
Hohenpeißenberg
- On the Hohen Peißenberg the mean annual temperature was 9 degrees Celsius).
The year was 2.5 degrees too warm, making it the warmest year since records began in 1781. The gap to the previous leader in 2018 is very small.
The highest temperature was measured on August 21, 2020 at 30.1 degrees.
It was coldest on March 23rd with -8.4 degrees.
The weather observers in the observatory on the Hohen Peißenberg recorded 18 summer days (maxima over 25 degrees) and one hot day (maxima over 30 degrees).
Frost occurred on 83 days.
Except for October (negative temperature deviation 0.2 degrees) all months were too warm.
In 2020, precipitation fell 1263 liters per square meter, four percent more than would have been expected over many years.
Months with particularly high rainfall were February (244 percent), June (151 percent), October (141 percent) and August (138 percent).
November (30 percent), December (48 percent), January (58 percent), April (58 percent) and May (60 percent) were far too dry.
However, 2020 was not only the warmest year since our records began, but with 2226 hours it was also the year with the most sunshine (sunshine statistics from 1937).
The sun worked 406 overtime hours, shining 22 percent more than the long-term average.
A snow cover was on 60 days, it was a maximum of 13 centimeters high.
There were thunderstorms for 34 days.
The storm of the year was the hurricane on February 10th with a wind peak of 40 m / s or 145 km / h.
In the further course, the past year was a year with little wind.
As the “guardian” and “sun room” of the foothills of the Alps, of course, climate change does not avoid the Hohen Peißenberg.
However, so far there has been no major drought, the rainfall balance is balanced.
The past decade was also the warmest on record.
Nine of the ten warmest years were in the 21st century.
The warmest six years took place after 2015.
Despite the corona lockdown, the concentration of greenhouse gases in the atmosphere continued to rise.
This fact, which has been proven by measurements, means a further significant warming of the climate for future generations, since the carbon dioxide has a long retention time in the atmosphere.
