“…The mean pressure reduced to sea level was 1,015.2 hPa and the mean wind speed at Koniczynka was a moderate 3.3 ms −1 . None of these values differed significantly from their long-term means (Kejna and Uscka-Kowalkowska 2018a), so they can be considered as representative of the area.…”

“…The spatial distribution of S↓ in the city was also studied (Kejna et al 2014a, b). In the suburban zone of the city of Toruń, at Koniczynka, measurements of S↓ were launched in 2001 as part of the Integrated Environmental Monitoring Programme (Kejna and Uscka-Kowalkowska 2018a), and since 2011, they have been extended to include measurements of Q* (Kejna et al 2014a, b).…”

The article contains an analysis of the influence of cloudiness and atmospheric circulation on the components of radiation balance (Q*) using the example of measurements taken in an extra-urban area of Koniczynka near Toruń (Central Poland) in the years 2011–2018. The average annual value of Q* was 1,818.5 MJ·m−2 with a maximum of 352.3 MJ·m−2 in June, and negative values from November to January (December: −27.4 MJ·m−2). The shortwave radiation balance (S*) amounted to 3,129.2 MJ·m−2 and the longwave radiation balance (L*) was ˗1,310.7 MJ·m−2. In June the average solar irradiance (S↓) at midday was 600 W·m−2. The natural annual and diurnal course of Q* components, determined by astronomical factors, is disturbed by changes in cloudiness and inflow of various air masses. It has been found that an increase in cloudiness causes the amount of incoming solar radiation (S↓) to fall, thus decreasing the S* balance. Moreover, clouds restrict longwave radiation balance (L*), in particular, downward atmospheric radiation (L↓) increases. The opposite relationships of S* and L* affect Q* in individual months. The components of Q* are influenced by atmospheric circulation; it has been observed that anticyclonic types, characterised by smaller cloud amounts, favour a greater influx of (S↓) and—at the same time—greater emittance (L↑); however, Q* is then greater than in the case of cyclonic circulation. A statistically significant trend of Q* and its components has not been ascertained. A notable great year-on-year variability of Q*, ranging from 1,640.4 MJ·m−2 (in 2011) to 2,081.6 MJ·m−2 (in 2018), affects the environment. The changes are related to the cloudiness and the frequency of occurrence of different atmospheric circulation types. The role of snow cover is also important as snow reflects solar radiation which leads to the decrease of S* and—as a result—to a negative value of Q* in winter.

“…An example of such situation is shown in Figure 8b. The research which was carried out at individual stations in Poland also showed that synoptic anticyclonic conditions with air mass inflow from the north and north-east, as well as south-west, prompt the largest GSR sums (Nelken, 2016;Kejna and Uscka-Kowalkowska, 2018).…”

“…In Poland, the influence of atmospheric circulation on GSR was only analysed in individual stations, for example in Belsk (Nelken, 2016) and Koniczynka (Kejna and Uscka‐Kowalkowska, 2018). So far, however, there has been no comprehensive study describing the influence of atmospheric circulation on the amount of GSR reaching the Earth's surface in Poland.…”

The key factor that affects the inflow of radiant energy to the Earth's surface is the circulation of the atmosphere (caused by uneven distribution of air pressure on the globe) and the related changes in the amount of aerosols and cloudiness. This paper identified the areas in the Euro-Atlantic region where the air pressure change had a significant impact on global solar radiation (GSR) changes over Poland, during the period 1986-2015. In general, growing GSR sums over Poland are to some extent related to the positive phase of the NAO (simultaneous pressure growth in the area of the Azores High and the pressure decrease in the area of the Icelandic Low). Correlation coefficient between the NAO index and GSR over Poland equals 0.18 (statistically significant at α = 0.05). In turn, in summer and autumn the pressure growth in southern Scandinavia results in a significant increase in the amount of GSR over Poland. Days with extremely large GSR sums (above the 95th percentile) are also prompted by the Azores High ridge which covers Central and Southern Europe, and by air mass inflow from the Atlantic.

“…The key factor that affects the inflow of radiant energy to the Earth's surface is the circulation (movement) of the atmosphere and the related changes in the amount of (both natural and anthropogenic) gases and aerosols contained in the atmosphere which reduce the inflow of solar radiation, as well as the associated cloudiness changes. The influence of atmospheric circulation on solar radiation was described by many researchers (Bryś and Bryś, 2001; Nelken, 2016; Parding et al ., 2016; Parding et al ., 2016; Kejna and Uscka‐Kowalkowska, 2018; Bryś and Bryś, 2019). Many observational and modelling studies suggest that the decrease in atmospheric aerosols concentration is the main driver of the modern increase in solar radiation (Streets et al ., 2006; Ruckstuhl et al ., 2008; Wild, 2016).…”

Incoming solar radiation is the most important factor shaping climate system on Earth and the main element of the surface heat balance. The main aim of this study was to investigate the changes in the amount of global solar radiation reaching the Earth's surface in Poland during the 30-year period 1986-2015. Trends in changes and fluctuations in the size of global solar radiation over Poland were determined. The solar radiation was described based on satellite products originating from the Surface Incoming Shortwave Radiation product from the Surface Solar Radiation Data Set-Heliosat, Edition 2 (SARAH-2). The average annual sum of global solar radiation over Poland amounted to 3,902 MJÁm −2. The average annual radiation sums were the smallest in northern Poland and mountain basins, while they were the largest in southern Poland. The average annual radiation sum over Poland increased by 7.16 MJÁm −2 Áyear −1 on average. The areas with the largest increase in the amount of solar radiation had the smallest average radiation sums during the multi-year period (Pomerania, Northern Poland), and those where the increase in radiation was moderate had the highest average radiation sums (Central and Southern Poland). This shows that the spatial differentiation of the amount of solar radiation over Poland was gradually decreasing during this period. A several-year cycle (of 12-13 years) of annual fluctuations in global solar radiation sums was observed using wavelet analysis. The cycle was visible between the early 1990s and 2005. It resulted from the medium-term cyclical component (an 11.3-year cycle which was the strongest until 2010) that occurred in summer. In the long term, the occurrence of cycles in the time series of solar radiation may result from cyclical or quasi-cyclical changes in aerosol concentration, but this requires a separate study and further in-depth research based on much longer data series.
