“…The values of the SPI and SRI are the standard deviation of precipitation and flows from the median value in the multi-year period. In the study, matching the normal distributions of homogenous series of precipitation P-1 was achieved with the use of the transformation function f(P) = 3 √ P [43]. In the case of calculating SRI-1, for the purposes of the normalization function, a two-parameter logarithmic function was used [8,21,43].…”

“…Extreme climatic events and their effects on the natural and social environment have become the most frequently discussed research problem in recent years. This is largely related to the serious impact of these phenomena on the functioning of people and the environment [1][2][3]. Europe has experienced numerous floods and droughts in recent years as a result of excesses and shortages of precipitation, contributing to significant economic losses.…”

This study used the standardized precipitation index (SPI) and the standardized runoff index (SRI) to analyze dry and humid conditions in the hill-country catchment area of the Laborec River (Slovakia) over a period of 50 years (1970–2019). Analysis of the SPI and SRI over various time scales showed the occurrence of wet periods (index > 1.0) that were associated with precipitation exceeding the long-term norm, and dry periods (index below −1.0), which were the result of small amounts of precipitation. Analysis of the correlation between the SPI and SRI on different time scales revealed that the catchment showed a weaker response to precipitation over short time scales (1 and 3 months) and a stronger response over longer accumulation periods (6, 9, and 12 months). The highest annual correlation coefficient (r = 0.72) was recorded between SRI-6 at the Humenne hydrometric station and SPI-9 at the Medzilaborce meteorological station in the upper part of the catchment area. The strongest annual correlation (r = 0.69) was obtained between the Izkovce and Kamenica stations in the lower part of the catchment area. As shown by the cross-relationships examined over different periods of accumulation of flows and precipitation, hydrological droughts appeared as a result of the occurrence of meteorological droughts with a three-month delay. The conducted analysis showed that in the case of the Laborec river catchment area, there was a strong correlation between the occurrence of meteorological drought and hydrological drought.

The article presents the course of meteorological droughts in Vistula subcatchments in years 1981–2010 and their influence on the occurrence of hydrological droughts. Using the Standardized Precipitation Index (SPI) as an indicator of meteorological drought on the one hand and the Standardized Water-level Index (SWI) and Standardized Runoff Index (SRI) as indicators of hydrological drought on the other, the mutual relationships between precipitation conditions and hydrological conditions were evaluated, as well as the relationships between the two drought types. Studies were conducted for three cumulative periods of these indices, of 12, 24, and 48 months. It was determined that meteorological droughts occurred earliest in the north-western and central part of the basin, and latest in areas lying above 300 m a.s.l. and in the south of Poland. Total duration, depending on the cumulative period, for SPI comprised from 38 to 41% of the analyzed period and for SWI (35–47%) and SRI (24–51%). The strongest relationships were identified in the central part of the Vistula (0.8 < r < 0.85), while the weakest relationships were recorded in the foothill region (r < 0.5). There were also indicated non-climate-related factors influencing those relationships (underground reservoirs, diverse Vistula water resource usage for municipal and industrial intake).

“…Note that the Vistula flowing through Kraków and Toruń is considered a factor shaping the urbanscape. Along its banks, there are river promenades, important components of green areas in both cities (Kubiak-Wójcicka et al, 2017). Most green areas are situated along the river or close to it.…”

Recent decades saw a global degradation of ecosystems and climate change caused by rapid anthropogenic socio-economic growth. The paper investigates spatio-temporal changes in green areas in Polish cities. The study involved two levels: macro (all 936 towns and cities in Poland) and micro (zooming in on Kraków and Toruń) from 2006 to 2018. The authors analysed 64,312 records of statistical data and 32,317 polygons representing areas of specific land use categories in the Urban Atlas with GIS tools and algorithms. Results for the entire country (a macro level) indicate that the area of forests in cities is in decline, but the total share of green urban areas is increasing slightly. Polish towns and cities also exhibit a positive balance of shrub count and a negative balance of tree count. At a micro level, land use analysis indicates a slight decrease in green urban areas, but an increase in the forest area. Moreover, an analysis of the spatial distributions of changes in green areas in Kraków and Toruń demonstrated specific trends. Sites exhibiting a significant decrease in green urban areas were found mainly along main transport routes. Moreover, incomplete green belts around highly urbanised zones turned out to be a characteristic component. The slight differences in results at a micro and macro level are due to a more significant generalisation at a macro level. Micro-level research focuses on an individual case. Hence, it should be used mainly to juxtapose cities, while the macro-level perspective is adequate for cross-country analyses, for example. The results are relevant to urban policies deployed by local and regional authorities, the European Green Deal and climate neutrality.
