The need for climatological data of the North Sea has increased during the past years. The increase in offshore and recreational activities can benefit greatly from such data. In order to meet this need weather observations made by ships and lightvessels in the North Sea have been processed extensively, which has resulted in a large number of tables, charts, etc. with climatological data. This publication gives a selection of these data, in which the emphasis lies on wind and wave data. In addition, some characteristic data on air and sea tempera ture, cloud cover, precipitation, visibility and sea level pressure are given. With regard to the observations of the lightvessels the publication can be consi dered as a continuation of earlier work. It also concludes the era of observations made by crew on board lightvessels, which gradually ended in the 1970's. The observations on fixed platforms which are now replacing the observations of the lightvessels are of a quite different character. The data are based on observations made on board lightvessels during the period 0 1949 -1980 and voluntary observing ships in the area between 51 ON and 60 N during the period 1961-1980. The observations of the lightvessels have been compared with those published for earlier periods (1859 -1883, 1884 -1909 and 1910 -1940). The manuscript (or part of it) has been critically examined by Prof.Dr.Ir. J.A. Battjes, E. Bouws, Dr.Ir. J.A. Buishand, H.A.M. Geurts, Dr. GJ.Komen, Dr. G.P.

Tropical atmosphere and ocean are receiving increased attention in relation to the functioning of the global climate system, the remarkable climatic variability in low latitudes, and the associated manifold environmental and societal consequences. Beyond the traditional emphasis of meteor ology on weather analysis and forecasting, there is a growing interest in the climate and large scale circulation of the tropics. This book may serve as a text for graduate and upper-division undergraduate students in meteorology, and is also intended as a reference work for practicing meteorologists, and researchers in the atmospheric, oceanic, and other environmental sciences. I began writing this book in 1979, but the roots reach further back. Early experiences in North Africa fuelled my curiosity about the low latitudes. In 1960 I seized the opportunity to work in the National Meteorological Service of El Salvador in Central America. My interest in the tropics continued after joining the University of Wisconsin in 1963. Field research brought me to the equatorial Pacific, and many times to the tropical Americas and Africa. This involved visits and correspondence with many weather services. My acquaintance with Australasia and South Asia is limited to short study visits, but includes continuous contacts with colleagues at key research institutions in India, namely the India Meteorological Department, the Indian Institute of Tropical Meteorology, and Andhra University. A guest semester at the University of the Witwatersrand in 1971 and related travels provided a perspective on the problems of Southern Africa.
