Download or read book Possibility of Long Range Precipitation Forecasting for the Hawaiian Islands written by Samuel B. Solot and published by . This book was released on 1948 with total page 60 pages. Available in PDF, EPUB and Kindle. Book excerpt: In order to establish a meteorological forecasting system, it is necessary to find a direct relationship between measurable physical states of the atmosphere and the end product, the weather element to be forecast. The long range forecaster is quite limited in his choice of physical parameters. In fact only the very large-scale dynamics of the atmosphere which can be expressed in terms of mean pressure patterns are amenable to long range analysis. Thus the problem reduces to finding a link between mean planetary pressure patterns and precipitation in the Hawaiian Islands.

Download or read book Application of Synoptic Climatology and Short range Numerical Prediction to Five day Forecasting written by William H. Klein and published by . This book was released on 1965 with total page 130 pages. Available in PDF, EPUB and Kindle. Book excerpt: Five-day mean and daily meteorological data observed since 1949 are analyzed empirically in order to derive useful climatological and forecasting relationships between surface weather elements and the circulation pattern. The synoptic climatology of 5-day precipitation, surface temperature, 700-1000-mb. thickness, and sea level pressure is investigated by constructing fields of simple linear correlation between these elements and the simultaneous anomaly of 700-mb. height over North American and adjacent oceans. The relation of precipitation and temperature to the field of sea level pressure is studied in a similar fashion. On the basis of the analogy are drawn concerning the association between each weather element and other meteorological factors. Schematic models are then constructed showing preferred portions of the circulation pattern at 700-mb. and sea level for opposite extremes of weather in different parts of the United States.

This book was released on 1949 with total page 68 pages. Available in PDF, EPUB and Kindle. Book excerpt: The investigation to be described in full in this report was started as a pilot project in July 1946, in an effort to improve and render more objective the precipitation anomaly estimates based on prognostic circulation patterns. Precipitation rather than temperature was investigated, because the forecast verification scores had been consistently lower on precipitation than on temperature forecasts.

Download or read book Predicting the Runoff from Storm Rainfall written by Max Adam Kohler and published by . This book was released on 1951 with total page 12 pages. Available in PDF, EPUB and Kindle. Book excerpt: The estimation of the volume of runoff to be expected from a given volume of rainfall is a fundamental problem in flood forecasting. Such estimates are necessary before the unit hydrograph or other techniques can be used to predict the streamflow hydrograph. The authors describe the technique now used at the River Forecast Centers of the U.S. Weather Bureau for evaluating the effect of season, antecedent conditions, duration of rainfall and rainfall amount in determining the portion of the rainfall contributing to storm runoff. Special problems encountered in flood forecasting are emphasized. The technique, developed and tested over several years, yields a high degree of accuracy in estimated runoff. Although prepared by empirical procedures, the close agreement between relations for basins of similar hydrologic characteristics suggests that rational parameter have been adopted. The similarity between relations also simplifies the work required for their preparation.

Download or read book Three dimensional Wind Flow and Resulting Precipitation in a Northern California Storm written by United States. Weather Bureau and published by . This book was released on 1963 with total page 56 pages. Available in PDF, EPUB and Kindle. Book excerpt: By careful consideration of the observed winds and with the aid of various empirical and dynamics relationships, a steady-state 3-dimensional wind flow is deduced over northern California for a 24-hour stormy period. The production (or evaporation) of precipitation elements is estimated for all parts of the flow, the surviving elements are followed down to the surface, and the resulting precipitation with the observed.

Available in PDF, EPUB and Kindle. Book excerpt: The second phase of the Cloud Physics Project was carried on in the vicinity of Wilmington, Ohio, during the spring and summer of 1948. The organization, facilities, and general mode of attack were the same as those used in the first phase of the project. In this second phase of the study, the basic objective was to determine in definite quantitative terms the practical limits and economic importance of cloud modification processes in producing precipitation from cumuliform clouds.

Available in PDF, EPUB and Kindle. Book excerpt: The basic objective of this Project was to determine in definite quantitative terms the practical limits and general utility of cloud modification processes in producing or suppressing precipitation and increasing the visibility from flying aircraft. In order that the effects of the induced modifications may be clearly separated from those occurring naturally, a closely coordinated attack using all available measuring facilities was adopted.

This book was released on 1961 with total page 96 pages. Available in PDF, EPUB and Kindle. Book excerpt: Long series of observations at climatological stations, commonly used for estimating secular climatic change, are frequently unsuitable for such an application. The purpose of this paper is to describe and apply an optimum methodology for measuring secular changes of temperature, by use of existing monthly mean data at cooperative climatological stations, with particular reference to the eastern United States.

Download or read book Mesoanalysis written by Tetsuya Theodore Fujita and published by . This book was released on 1956 with total page 96 pages. Available in PDF, EPUB and Kindle. Book excerpt: "The primary purpose of this paper is to present a significant scale of meteorological events. This scale, the mesoscale, is either overlooked or intentionally ignored in much of the analysis being done today. The reason normally given for this omission is the fact that these meteorological motions are essentially 'noise' superimposed on larger-scale circulations and it is with these larger-scale circulations that most of the meteorologists' efforts (both theoretical and synoptic) have been concemed. It is our opinion, however, that this 'noise' is directly tied up with the local weather and that the meteorologist will have to despair of ever being able to predict this local weather with a satisfactory degree of confidence unless he has accurnte knowledge of what is going on in the mesometeorological scale of motion. In addition to focussing the readers attention on this scale of motion, it is also the purpose of this paper to serve as a preliminary manual for mesoanalysis. Although most of the analysis techniques have been given elsewhere (T. Fujita, 'Results of Detailed Synoptic Studies of Squall Lines', Tellus, vol. 7, No. 4, 1955, pp. 405-436), they are described fully here for completeness. Moreover, all of the ditta used in the analysis have also been reproduced in the form of station time sections. It is intended that these will serve two purposes: (1) The reader is encouraged to follow the techniques presented, perform his own mesoanalyses and compare them with the results given here, and (2) the reader will be able to interpret the sequence of events as they transpired at any station in terms of the mesosystems, developed in the analysis, which passed the station. Finally, we wish to point out that we have concerned ourselves here with analysis and not with explanation. The analyses clearly show the formation, development, movement, and dissipat ion of mesostruct ures. From this point of view the primary purpose of the paper is realized. However, there still remains the problem of explaining the life history of the mesostrnctures from a dynamical point of view"--Preface

Book excerpt: The underlying concept of the paper is that the amount of precipitation required for the near-normal operation of the established economy of an area during some stated period is dependent on the average climate of the area and on the prevailing meteorological conditions both during and preceding the month or period in question. A method for computing this required precipitation is demonstrated.
