The dry climate that prevailed during the Triassic period in the eastern part of the Central European Basin was interrupted by several humid episodes of varying durations. One of them was the Carnian Pluvial Episode (CPE), which took place in the late Julian (early Carnian age) and is confined to Camerosporites secatus and Aulisporites astigmosus palynological zones. CPE is marked by a significant change in the qualitative and quantitative composition of spore-pollen assemblages from mostly xerophytic species preserved in the upper part of the Grabfeld Formation (“Lower Gipskeuper”) to hygrophytic forms, which dominate in the Stuttgart Formation (“Schilfsandstein”). Changes in climate towards more humid conditions have been documented palynologically and sedimentologically, and analyzed utilizing quantitative spore-pollen analysis and Principal Component Analysis (PCA) of miospores occurring in core material from Poland. In all the studied boreholes, a shift from dry to wet climate is observed at the boundary between the Grabfeld Formation and the Stuttgart Formation, which matches the data from other European regions.

中欧盆地东部三叠纪盛行的干旱气候被持续时间不同的几次潮湿事件所打断。其中之一是《嘉年华雨季》（CPE），发生在朱利安时代晚期（嘉年华早期），仅限于喀麦隆孢子虫（Camerosporites secatus）和金刚孢虫（Aulisporites astigmosus）孢粉区。CPE的特征是孢子花粉组合的定性和定量组成发生了显着变化，从保留在Grabfeld组上部（“下Gipskeuper”）的大部分旱生植物变成了以斯图加特组（“ Schilfsandstein”为主）的吸湿形式。 ”）。在孢粉学和沉积学上已记录了气候向更湿润条件的变化，并利用波兰孢子的定量孢子-花粉分析和主成分分析（PCA）进行了分析。在所有研究的钻孔中，在格拉布费尔德组和斯图加特组之间的边界都观察到了从干燥气候向潮湿气候的转变，这与来自其他欧洲地区的数据相吻合。
