In the first half of 2020, the average monthly temperature in Siberia reached 6 ° C. The situation rose on June 20, when the temperature in the city of Verdhansic climbed at 38 ° C (100.4 ° F), which is recorded in the north of the Arctic circle ever. With extreme heat, forest fires, insects, and melting Perma came with the frost.
Now Rubon Et al. Recommend that the effects of 2020 heat wave were also identified in the form of hot and wet and abnormal soil next year.
Researchers obtained data related to temperature, rain and other climate factors from the European Center to forecast medium -sized weather and added them to the model of high longing environmental system. The 2020 Siberian to achieve the effect of the heat wave, they replaced the data with data from 2020 to the last 5 years (2015 to 2019), providing five estimates that looked like a regional environmental system, such as the heat wave in 2021.
The analysis indicated that the soil temperature due to high heat is about 1.2 ° C, or about 150 150 %, which occurs in 2021 without a heat wave, though the air temperature returned to normal. Hot temperatures also melted the soil ice, which resulted in more wet soil than usual. The availability of route zone soil water, a measure of how much water can hold in the depths of the root of the plants, the forests increased by 10.9 % and the grass field increased by 9.3 %. However, some of this melt water left the soil through the run -off.
In response to hot, wet soil, microbes spread and the soil ecosystem emitted more carbon dioxide than usual, the modeling indicated. In the forests, this effect was largely presented by the increase in photoshocytes as plants grow in new conditions. On the other hand, in the grass field, photos of the heat wave increased during the heat wave, but then decreased sharply by 2021 as the plants used the water available and died. As a result of the 2020 heat wave, the researchers reported, the forests obtained 6 grams of carbon per square meter per square meter in the first half of 2021, while the Grasslands lost 10.9 grams of carbon per square meter.
