abstract = {The frequency of snowfall and rainfall is expected to change due to the warming climate. However, trends in liquid and solid phases are not linearly related to air temperature trends. This paper discusses the impact of thermal properties of circulation types (CTs) on the trends in snowy and rainy days in Poland in the period 1966-2020. The visual observations from 42 synoptic stations, which constitute the most-reliable information on precipitation type, were used to identify the precipitation phase.

The rate of tendencies in the probability of the precipitation phases depended on the average temperature and the intensity of warming, in particular CTs.

abstract = {In Poland the phase in which precipitation occurs impacts the availability of water in its reservoirs, the potential for hydrological droughts, snowfall flooding and winter recreation. The influence of warming on the occurrence of precipitation phases on the Polish scale has not been studied so far. Based on data from 42 synoptic stations for the period 1966–2020, this study discusses trends in the indices of liquid (Lq), mixed (Mx) and solid (Sd) precipitation describing their totals (T), frequencies (Nd) and contribution to overall precipitation totals (T%) and a number of days with overall precipitation (Nd%) from a seasonal perspective. Moreover, the influence of seasonal and daily air temperatures on long-term variability in the precipitation phase indices was assessed. The precipitation phase was discriminated based on the observations of weather phenomena noted as current and past weather considering days with precipitation ≥ 0.1 mm. Precipitation phases significantly reacted to current warming. The strongest and widespread were increasing trends in rains (+1.74 for LqNd; +5.35 mm for LqT; +3.51% for LqNd%; +4.08% for LqT% per decade) and decreasing trends in snowfalls (−1.92 for SdNd; −3.12 mm for SdT; −3.65% for SdNd%; −3.26% for SdT% per decade) in winter when the warming was weakest but average temperature was close to freezing point. In winter, air temperature explained 60%–80% of the variance in the frequency of snowfall and rainfall. Daily air temperature > –2 °C contributed to trends in winter rainfall while daily air temperature > 1 °C most contributed to trends in winter snowfall. No trends in winter mixed precipitation were due to opposite changes in its frequency above and below 1 °C. In spring, the increase in a liquid phase was due more to the melting of a solid and mixed phase, while in autumn, it was due more to the transformation of a mixed phase into a liquid phase. In spring, air temperature explained at most 30%–50% of the variance in the indices of snowfall frequency. Negative trends in mixed precipitation were significant in transitional seasons, being more prominent in spring than in autumn and were mostly driven by changes in daily air temperatures between 0 and 5 °C.

The locale was a gradient meteorological station, 4 m and 100 m above ground. The dominant compounds identified were anhydro-, mono- and disaccharides which were divided into three groups of organic tracers (OT): biomass burning (BB) including low-rank coal burning, pollen grains (PG) and fungal spores (FS). The BB group included: levoglucosan, mannosan and galactosan, complemented with vanillic and dehydroabietic acids. The PG group included: fructose, glucose and sucrose, supplemented with D-pinitol, and the FS tracers included: arabitol, mannitol and trehalose. Levoglucosan reached 1503 ng/m3 in heating season at 4 m and 983 ng/m3 at 100 m. These values are among the highest mean concentrations of levoglucosan reported in Europe, confirming severe pollution of the Upper Silesian urban environment. We also suggest that the significant levoglucosan levels during the non-heating seasons could be from wind advected polluted soil and dust. All FS tracers correlate well with fungal spore counts, while the correlation of pollen numbers with their typical molecular tracers is statistically less significant. Weather conditions significantly influence the concentration of OT in aerosols. Among these, air temperature is a factor that affects the occurrence/existence of OT in the atmosphere, while temperature inversions are the main phenomenon which determines elevated concentrations of pollutants and their vertical variation in ambient air. For example, the concentration of BB tracers can be twice as high at 4 m as at 100 m under moderate to strong temperature inversions associated with low wind speed. Water vapor pressure and sun irradiation are also important factors controlling OT concentrations.

abstract = {This contribution provides the basics of the climatology of the Polish Tatra Mountains in a nutshell, with particular reference to intense precipitation and its relation to atmospheric circulation. Variability of various precipitation characteristics, including selected indices of intense precipitation in Zakopane and at Kasprowy Wierch, is illustrated in this paper. None of the trends in these characteristics and indices calculated for the entire time interval exhibit a statistical significance, but short-time fluctuations are evident. The occurrence of intense precipitation in the Tatra Mountains is strongly related to three circulation types. These situations (Nc; NEc; Bc) are associated with cyclones following track Vb after van Bebber.

This contribution provides the basics of the climatology of the Polish Tatra Mountains in a nutshell, with particular reference to intense precipitation and its relation to atmospheric circulation. Variability of various precipitation characteristics, including selected indices of intense precipitation in Zakopane and at Kasprowy Wierch, is illustrated in this paper. None of the trends in these characteristics and indices calculated for the entire time interval exhibit a statistical significance, but short-time fluctuations are evident. The occurrence of intense precipitation in the Tatra Mountains is strongly related to three circulation types. These situations (Nc; NEc; Bc) are associated with cyclones following track Vb after van Bebber. In addition to changing frequencies of circulation, this study also reveals an increase in the frequency of the circulation types associated with extreme precipitation. © 2014, The Author(s).

abstract = {This paper aims at recognizing spatial differentiation in probability of ice days occurrence with reference to atmospheric circulation, using regional classification of circulation types for Poland. Daily maximum air temperatures measured at nine meteorological stations were used to recognize the ice days occurrence in the period from January 1951 to March 2014. The relations between the ice days occurrence and atmospheric circulation were analysed using catalogues of circulation types compiled for nine grid boxes within Poland. Linkage between the frequency of ice days and atmospheric circulation was recognized in the period of January 2001 - March 2014. A decreasing tendency in the frequency of the occurrence of winter ice days was found. The occurrence of ice days in Poland is clearly related to atmospheric circulation. In the entire area of Poland their occurrence is favoured by eastern and south-eastern advection of air during anticyclonic conditions (types Ea nad SEa).

An important component of the framework is the assessment of the "metauncertainty" arising from the structural uncertainties of a linked sequence of climate, production, trade and decision-making models.
