Abstract The following article presents the results of research on the influence of atmospheric circulation on air temperature and atmospheric precipitation in the Bydgoszcz-Toruń region (Poland) in the period 1921-2000. In order to do this, we have constructed a daily calendar of synoptic situations using criteria proposed by Niedźwiedź (1981). Daily values of air temperature and atmospheric precipitation were collected from the meteorological station in Toruń. Research results show that weather conditions in the study area are influenced predominantly by the direction of air mass advection and, to a lesser extent, by the prevailing type of isobaric system.

Large Scale Atmospheric Circulation

The main results of the analysis of the Northern Hemisphere large-scale atmospheric circulation features are presented for the 2020 summer. Skill scores of the consensus forecast for the 2020 Northern Eurasia summer are discussed in the context of analyzing the large-scale atmospheric circulation. The prognostic potential of the trend component in forecasting seasonal anomalies of air temperature and precipitation is noted.

Disastrous Flood

According to the circulation seasons [Dzerdzeevsky et al., 1946], according to the website Weather News, extreme events in the Asian territory of Russia for first half of 2019 were considered: daily maximums and minimums of air temperature; maximum daily amplitudes of air temperature, daily maximums and monthly lows of atmospheric precipitation; daily maximums wind speeds, maximum and minimum of snow depths and dangerous natural processes. Their connection with the atmospheric circulation of the Northern Hemisphere has been shown [Atmospheric Circulation fluctuations site 18992018]. In recent years, extreme situations are increasingly becoming apparent in the Asian part of Russia. This attracts the close attention of researchers [Latysheva et al., 2010; Zolina, Bulygina, 2016]. They try to identify the causes of what is happening [Vasilyev et al., 2018; Kononova, 2018; Kochugova, 2018; Tarabukina et al., 2018] and predict the future nature of extrema [Shkolnik et al., 2012]. It seemed interesting to analyze the extremes of the current year (more precisely, the first half of it), to show the real situation today. The majority of extremes, surpassed in the first half of 2019, refers to the 21st century. This means that extremity has been growing rapidly in recent years. The consequence of this is an increase in the frequency of occurrence of dangerous natural processes. The main source of information on daily meteorological extremes was Weather News [Meteonovosti.ru]. It briefly informed about fires and floods. More detailed information was taken from local sites [Amur.Info, Taiga.Info, Ulpress.ru, Social media news]. The character of atmospheric circulation was analyzed by classification [Dzerdzeevsky et al., 1946] using data from the site of the Atmospheric Circulation fluctuations.. for 1899 2018 The most disastrous flood was June 24 - 29 in the Irkutsk region. It destroyed more than 10,000 residential homes in 98 settlements, 43 schools, kindergartens and hospitals. According to information on July 11, 25 people died. The strongest were fires in the Krasnoyarsk Territory and the Irkutsk Region in the third decade of July. Smoke from them reached the Ulyanovsk region. The conducted research allows to draw the following conclusions. The number of extremes of both air temperature and precipitation in the XXI century continues to grow. Negative extremes of precipitation in combination with positive extremes of air temperature lead to natural fires, positive extremes of precipitation - to catastrophic floods. The increasing frequency of atmospheric circulation contributes to an increase in the frequency of occurrence of those and others: an increase in the frequency of occurrence of blocking processes (arctic invasions resulting in the formation of a vast stationary anticyclone) and exits of southern cyclones.

Climatic features of the 2020/2021 winter season and the air temperature and precipitation outlook for the summer of 2021 over Northern Eurasia / Khan V.M., Vilfand R.M., Emelina E.V., Kaverina E.S., Kulikova I.A., Sumerova K.A., Tischenko V.A. // Hydrometeorological Research and Forecasting, 2021, no. 2 (380), pp. 6-19. The main features of the Northern Hemisphere large-scale atmospheric circulation are analyzed for the past 2020/2021 winter. The accuracy of consensus forecasts of air temperature and precipitation compiled during the work of the 19th session of the North Eurasian Climate Outlook Forum (NEACOF-19) is presented, with the skill scores of consensus forecasts for Northern Eurasia. The main features of the thermal state of the ocean and large-scale atmospheric circulation for the coming summer of 2021 are considered and analyzed. A forecast of surface air temperature and precipitation anomalies for the summer of 2021 agreed with the NEACOF-20 experts is formulated.
