Dryness and wetness variations on different time scales in Shangai were analyzed using the Standardized Precipitation Index (SPI) based on monthly precipitation data for 1873-2005. The SPI on 3, 6, 12 and 24 months has been calculated. They present
4 wet periods prevailed during 1873-1885, 1904-1923, 1938-1960 and 1983-2005, and 3 dry episodes during 1886-1903, 1924-1937 and 1961-1982. Significant periods of higher wavelet power in the SPI-24 months occurred on the time scales of 2-7-year band
in around 1880-1890, 1910-1950 and 1970-1990, and at 8-15-year band in 1920-1960 and 1965-2000 respectively. Periodicities in the SOI and ENSO indices are similar to those in SPI-24 months. The periodicity components in individual SPI-24 months, SOI and ENSO

Franz Josef Land was discovered on 30th August 1873 by an Austro-Hungarian Expedition. The A. describes the story of this 1872-1874 Tegetthof expedition, which was originally destined for the North Pole, but had as its ultimate intention
the discovery of a Northeast Passage to the Far East. However, while caught in the grip of the ice for some two years, the expedition unexpectedly came upon Franz Josef Land, spending seven months of winter 1873–1874 there. Unsurprisingly, the expedition’s
Comparing with other German countries a land survey of Mecklenburg on the basis of scientific fundaments was performed very late, from 1853-1873. The author was F. Paschen. His order net was integrated into the Prussian National Survey. - (IH)
