This year has brought a real Indian summer. In continental climate, this warm and colorful period is usually limited to September. Later on, it is hard for the temperature to reach +15...+20 (otherwise, it won’t be considered summer). But now the mercury has exceeded +20 in the Urals and Siberia.
This unusually warm weather is caused by Atlantic cyclones in the north and the former Azores High in southern Siberia. Together, these weather systems are spreading waves of subtropical heat, resulting in heat records in Yekaterinburg, Khanty-Mansiysk, Omsk, and Novokuznetsk.
It should be noted that the weather is calm and anticyclonic, which is typical for Indian summer. There are clear skies, weak winds, and a large diurnal temperature range in the anticyclone area. Near-zero temperatures are recorded at night, while in the afternoon, the mercury rises to +20. For example, Novosibirsk saw a temperature of +22 on October 6.
