    Ponencia presentada en: VI Congreso Internacional de la Asociaci贸n Espa帽ola de Climatolog铆a celebrado en Tarragona del 8 al 11 de octubre de 2008.[ES]En este articulo se presenta la reconstrucci贸n de algunos fen贸menos atmosf茅ricos (precipitaci贸n, tormentas, nieblas) en la Comunidad Polaco-Lituana para el periodo 1658-1667 basada en el diario escrito de Jan Antoni Chrapowicki. Las anotaciones meteorologicas diarias realizadas durante este periodo permiten el calculo de las frecuencias para algunos de los fen贸menos investigados. Para prop贸sitos del an谩lisis, las frecuencias mensuales, estacionales y anuales de la ocurrencia de d铆as con precipitaci贸n, tormentas, granizadas y nieblas han sido calculadas. La evoluci贸n anual de la frecuencia de ocurrencia de estas variables revelan los mismos patrones que en el clima actual. Tampoco hay cambios significativos entre el periodo hist贸rico y el actual en el numero de dias al a帽o con precipitaci贸n y granizo. Por otro lado, los valores absolutos de d铆as con tormentas y nieblas fueron apreciablemente m谩s bajos en el per铆odo del estudio que en la actualidad. Parece que esta diferencia puede ser explicada, por lo menos parcialmente, por el hecho de que el clima de Polonia en el siglo XVII fue m谩s fr铆o y m谩s continental.[EN]The paper presents a reconstruction of some weather phenomena (precipitation, thunderstorms, hailstorms, fogs) in the Polish-Lithuanian Commonwealth for the period 1658-1667 based on a diary written by Jan Antoni Chrapowicki. Daily weather notes made by him during this period permitted the reliable calculation of frequencies for at least for some of the weather phenomena which were investigated. For purposes of analysis, the monthly, seasonal, and annual frequencies of occurrence of days with precipitation, thunderstorms, hailstorms and fogs have been counted. The annual courses of frequency of occurrence of these variables reveals the same pattern of changes as in today鈥檚 climate. Also there are no significant changes between the annual number of days with precipitation and hailstorms in the historical and present-day periods. On the other hand, absolute values of days with thunderstorms and fogs were significantly lower in the study period than they are today. It seems that this difference can be explained, at least partially, by the fact that the climate of Poland in the 17th century was colder and more continental than .The research in the present paper was funded by a grant obtained from the State Committee for Scientific Research (grant no.

    The last millennium climate change in Northern Poland derived from well temperature profiles, tree-rings and instrumental data

    Get PDF
    In order to reconstruct the air temperature variations in Northern Poland for the last millennium observational and proxy (tree-ring widths) data were used. For the first time the ground surface temperature (GST) for Northern Poland was reconstructed based on geothermal data (well temperature profiles). A general warming trend is observed for both the GSTH (GST Histories) derived from geothermal data and instrumental data, in particular, for the last 200 years

    Temperature changes in Poland from the 16th to the 20th centuries

    A standardized tree-ring width chronology of the Scots pine (Pinus sylvestris L.) along with different types of documentary evidence (e.g. annals, chronicles, diaries, private correspondence, records of public administration, early newspapers) have been used to reconstruct air temperature in Poland. The ground surface temperature (GST) history has been reconstructed based on the continuous temperature logs from 13 wells, using a new method developed recently by Harris and Chapman (1998; Journal of Geophysical Research 103: 7371鈥7383) which is compared with the functional space inversion (FSI) method applied to all available Polish temperature鈥揹epth profiles analysed before. Response function calculations conducted for trees growing in Poland (except in mountainous regions) reveal a statistically significant correlation between the annual ring widths of the Scots pine and the monthly mean air temperatures, particularly from February and March, but also from January and April. Therefore, it was only possible to reconstruct the mean January鈥揂pril air temperature. The following periods featured a warm late winter/early spring: 1530鈥90, 1656鈥70 (the warmest period), 1820鈥50, 1910鈥40, and after 1985. On the other hand, a cold January鈥揂pril occurred in the following periods: 1600鈥50, 1760鈥75, 1800鈥15, 1880鈥1900, and 1950鈥80. Reconstructions of thermal conditions using documentary evidence were carried out for winter (December鈥揊ebruary) and summer (June鈥揂ugust) from 1501 to 1840 and, therefore, their results cannot be directly compared with reconstructions based on tree-ring widths. Winter temperatures in this period were colder than air temperature in the 20th century. On the other hand, 鈥榟istorical鈥 summers were generally warmer than those occurring in the 20th century. Such situations dominated in the 16th and 17th centuries, as well as at the turn of the 18th and 19th centuries. Throughout almost the entire period from 1501 to 1840, the thermal continentality of the climate in Poland was greater than in the 20th century. GST reconstructions show that its average pre-instrumental level (1500鈥1778) is about 0.9鈥1.5 掳C lower than the mean air temperature for the period 1951鈥81. Lower amplitude of GST warming (0.9 卤 0.1 掳C) results from the individual and simultaneous inversions of well temperature data using the FSI method. A very good correspondence of the results has been found between series of annual mean GSTs from the FSI method and mean seasonal air temperatures reconstructed using documentary evidence
