Some New Methods in Meteorology

Some New Convergence Acceleration Methods

The £-algorithm is a general extrapolation method which includes most of the sequence transformations actually known. Some new convergence acceleration methods are derived from the f-algorithm by applying the so-called (^-procedure. The algorithms thus obtained are studied. Some theoretical results are proved and numerical examples are given.

Some New Methods of Radiotherapy

There have been many advances in treatment with X-Rays and radioactive su stances. This is an account of those recently adopted and those to be used in futu in the Radiotherapy Department at Bristol. t There are two great difficulties in using Deep X-Rays for the treatment of maligna disease. First, " Deep " X-Rays do not penetrate really deeply. Their effective rafl& is a few centimetres deepe...

Some New Methods for Prediction of Time Series by Wavelets

Extended Abstract. Forecasting is one of the most important purposes of time series analysis. For many years, classical methods were used for this aim. But these methods do not give good performance results for real time series due to non-linearity and non-stationarity of these data sets. On one hand, most of real world time series data display a time-varying second order structure. On th...

Some Statistical Physics Approaches for Trends and Predictions in Meteorology

Specific aspects of time series analysis are discussed. They are related to the analysis of atmospheric data that are pertinent to clouds. A brief introduction on some of the most interesting topics of current research on climate/weather predictions is given. Scaling properties of the liquid water path in stratus clouds are analyzed to demonstrate the application of several methods of statistic...
