“…Similar results were obtained while analysing frost occurrence in different areas of Poland, among others, in Szczecin Lowland [26], in the area of Bydgoszcz [16], in North-Eastern Poland [22] and in Poland as a whole [20,27]. Schein ger et al [15] while analysing the occurrence of last frosts in spring in Central Europe between 1951 and 1997, also showed that it occurred increasingly early, at a rate of 0.2 day·year − .…”

Abstract:The main objective of this article is to analyse the multiannual variability of frost occurrence and the length of the frost-free period in Poland and neighbouring countries between 1971 and 2010. A frost day was dened as a day on which the minimum temperature was below 0°C and the maximum temperature was above 0°C. On average, between March and November, there were 30 frost days in Poland and neighbouring countries, and their number ranged between 12 and 61. In the analysed multiannual period, there was a statistically signi cant tendency for the last spring frost to be earlier. Conversely, the rst autumn frost occurred increasingly late, although the changes were not statistically signi cant. All but three stations (Augsburg, Kaliningrad, Olsztyn) recorded an increase in the length of frost-free periods, which was statistically signi cant in 51% of stations. The pressure condition conducive to the occurrence of frosts was anticyclonic circulation, as con rmed by the SLP and z500 hPa maps which were drawn up, and the Grosswetterlagen (GWL) classi cation types which were distinguished.

“…Dry periods are related to the atmospheric circulation patterns and can affect large areas . In temperate and boreal climates the effect of water shortage on vegetation is not as significant as in arid or semiarid areas, but there is strong evidence of water deficit effect on various types of vegetation in the study area (Kulikauskas and Sprainaitiene, 2005;Vitas and Erlickyte, 2008;Ozolincius et al, 2009;Kalbarczyk, 2010;Bijak, 2011).…”

Drought identification in the eastern Baltic region using NDVI

Abstract. Droughts are phenomena that affect large areas. Remote sensing data covering large territories can be used to assess the impact and extent of droughts. Drought effect on vegetation was determined using the normalized difference vegetation index (NDVI) and Vegetation Condition Index (VCI) in the eastern Baltic Sea region located between 53-60 • N and 20-30 • E. The effect of precipitation deficit on vegetation in arable land and broadleaved and coniferous forest was analysed using the Standardized Precipitation Index (SPI) calculated for 1-to 9-month timescales. Vegetation has strong seasonality in the analysed area. The beginning and the end of the vegetation season depends on the distance from the Baltic Sea, which affects temperature and precipitation patterns. The vegetation season in the southeastern part of the region is 5-6 weeks longer than in the northwestern part. The early spring air temperature, snowmelt water storage in the soil and precipitation have the largest influence on the NDVI values in the first half of the active growing season. Precipitation deficit in the first part of the vegetation season only has a significant impact on the vegetation on arable land. The vegetation in the forests is less sensitive to the moisture deficit. Correlation between VCI and the same month SPI1 is usually negative in the study area. It means that wetter conditions lead to lower VCI values, while the correlation is usually positive between the VCI and the SPI of the previous month. With a longer SPI scale the correlation gradually shifts towards the positive coefficients. The positive correlation between 3-and 6-month SPI and VCI was observed on the arable land and in both types of forests in the second half of vegetation season. The precipitation deficit is only one of the vegetation condition drivers and NDVI cannot be used universally to identify droughts, but it may be applied to better assess the effect of droughts on vegetation in the eastern Baltic Sea region.

“…Most of the scientific investigations are concentrated on the spatial and temporal distribution of droughts (Hisdal et al 2001;Loyd-Hughes, Saunders 2002; and on the impact of droughts on hydrological cycles (Bordi et al 2009;Wilson et al 2010;Tallaksen et al 2011). Droughts are analyzed in a very wide context of scientific researches: drought impact on agro-ecosystems (Sakalauskaitė 2006;Schindler et al 2007;Kalbarczyk 2010;Rad, Zandi 2012) and on forest life (Maracchi et al 2005;Lindner et al 2007;MacKay et al 2012); interactions with water bodies (Peters et al 2006;Jakimavičius, Kovalenkovienė 2010;Hän-ninen, Vuorinen 2011) and water quality (Sakalauskiene, Ignatavicius 2003;van Vliet, Zwolsman 2008;Zielinski et al 2009). Palaeoclimatological drought conditions are discovered using sediments (Dippner, Voss 2004) and tree rings (Vitas, Erlickytė 2008;Bünt-gen et al 2010;Drobyshev et al 2011) data analysis.…”

The dynamics in dryness over the Baltic Sea region during the observation period of 1960-2009, as well as the climate prediction for the 21 st century have been evaluated in this research. The dryness of the investigated area has been examined using the Standardized Precipitation Index (SPI). The precipitation amount data provided by the Climate Research Unit (CRU) at the University of East Anglia have been used in this study. Projections of future dryness changes are based on the output data of the regional CCLM model driven by A1B and B1 emission scenarios. The increase of SPI values, i.e. a decline in dryness, have been found over the last fifty years in the major part of the investigated area. However, the probability of short-term droughts remain high against the background of a general decrease in dryness. The increased dryness during the analyzed period has been found only in the southern part of the Baltic Sea region. Similar changes are also foreseen for the 21 st century. The dryness is expected to increase in the south (especially in summer), while the central and northern parts of the region are likely to witness the recurrence of a drought decrease.
