Forecasting the weather for the long and medium range is a difficult and scientifically challenging problem. Since the first operational weather prediction by numerical methods was carried out (on the BESK computer in Stockholm, Sweden, 1954) . there has been an ever accelerating development in computer technology. Hand in hand has followed a tremendous increase in the complexity of the atmospheric models used for weather prediction. The ability of these models to predict future states of the atmosphere has also increased rapidly, both due to model development and due to more accurate and plentiful observations of the atmosphere to define the initial . state for model integrations. It may however be argued on theoretical grounds that even if we have an almost perfect model with almost perfect initial data, we will never be able to make an accurate weather prediction more than a few weeks ahead. This is due to the inherent instability of the atmosphere and work in this field was pioneered by E. Lorenz. It is generally referred to as atmospheric predict ability and in the opening chapter of this book Professor Lorenz gives us an overview of the problem of atmospheric predictability. The contributions to this book were originally presented at the 1981 ECMWF Seminar (ECMWF - European Centre for Medium Range Weather Forecasts) which was held at ECMWF in Reading, England, in September 1981.

In 1985, the U.S. aerospace industry achieved a $13.1 billion trade surplus and contributed $89.2 billion in shipments to the U.S. economy. Without·aerospace, the U.S. trade balance in high technology industries would--for the first time--have fallen into a deficit. Civil aircraft play a significant role in the U.S. aerospace industry, and U.S. civil aircraft have dominated world markets (particularly the large transport segment) since the development of jet engine aircraft in the 1950s. This dominance has recently been challenged by the emergence of the European Airbus Industrie, which has achieved a significant market position in wide-body aircraft and appears committed to the development of a diversified family of civil aircraft. Industry observers are also concerned about the possibility of Japan entering the large transport competition. In this assessment, the U.S. Department of Commerce examines the prospects for continued international competitiveness of U.S. civil aircraft. The report identifies key factors that will determine the shape of future competition, develops alternative scenarios for the future, and presents-a framework within which developments can be monitored and measured.

There is growing concern among scientists, farmers and the general public that pesticides are being applied ever more widely but with less and less discretion. This book brings together a range of experts to discuss how crop protection chemicals can be used more rationally, so as to maximise benefits in yield and quality while minimising environmental and economic costs. The book is based on the ninth Long Ashton Symposium and is organised into four sections. The first, environment, examines to what extent current pesticide use is affecting the environment and human welfare, and what changes in practice are justified. The second, application, assesses progress in performance and safety in the use of pesticides, while the next section, resistance, looks at problems and shortcomings arising from the appearance of resistant strains of pests, and considers strategies for surmounting these difficulties. The final section, forecast and pest management, asks whether existing methods of assessing risks are acceptable and seeks ways of rending decision making in crop protection more rational.

Urban problems are now a dominant social issue: the essays in this volume consider the direction some of these problems may take in Central Canada. Three broad themes are discussed: forecasting (a spectrum of methodologies and urban forecasts); assessing the consequences of these forecasts at two levels (the growth of cities as an urban system and the growth and form of individual cities or urban regions); and assessing the role of changes in public policy. Specific topics include forecasting methodology in a spatial context, population and employment growth, migration, transportation, innovations, communication linkages, regional economic structure, economic fluctuations, the effects of public policy controls within a system of cities, land use and redevelopment, household mobility and social change, the spread of urban fields, and communities and neighbourhoods within cities.
