This book was released on 1976 with total page 30 pages. Available in PDF, EPUB and Kindle. Book excerpt: Differences between mean monthly winds obtained from actual observations and geostrophic wind derived from mean monthly altitudes of constant-pressure surfaces are examined for January and July at four levels between 10,000 and 40,000 ft. Differences in speed for both east-west and north-south components are significantly and unexpectedly large. These results demonstrate the advantage of using observed winds rather than deduced values to provide climatic winds at altitudes betweet 10,000 and 40,000 ft. Modification of the existing system to include winds from actual observations wherever and whenever possible is recommended. (Author).

Available in PDF, EPUB and Kindle. Book excerpt: Geostrophic wind components computed from monthly mean atmospheric sea level pressure charts are employed as indices of wind intensity over the principal current systems in the North Pacific Ocean. Pressure differences across pairs of points at 36 locations and deviations from long-term monthly means are tabulated for a 33-year period, 1926-58. The data for certain locations were combined to form regional indices representing wind components tangential to the major North Pacific Ocean currents. The mean seasonal cycles of these indices show marked differences in phase and amplitude for the various regions. Monthly anomalies are found to have generally larger magnitudes in winter months than in other seasons. Some evidence of long-term trends is indicated by graphical representation of time series and decade means. In particular, weak wind components occurred over the Oyashio and Alaska currents during the winter months of the period 1946-55, while over the California current the wind components were stronger, than during the previous decade.

Download or read book Determination of Wind from NIMBUS 6 Satellite Sounding Data written by William E. Carle and published by . This book was released on 1981 with total page 88 pages. Available in PDF, EPUB and Kindle. Book excerpt: Objective methods of computing upper-level and surface wind fields from Nimbus-6 satellite sounding data are developed. These methods are evaluated by comparing satellite-derived and rawinsonde wind fields on gridded constant-pressure charts in four geographical regions. Satellite-derived and hourly observed surface wind fields are compared. Results indicate that the best satellite-derived wind on constant-pressure charts is a geostrophic wind derived from highly smoothed fields of geopotential height. Satellite-derived winds computed in this manner and rawinsonde winds show similar circulation patterns except in areas of small height gradients. Magnitudes of the standard deviation of the differences between satellite-derived and rawinsonde wind speeds range from approximately 3 to 12 m/s on constant-pressure charts and peak at the jet-stream level. Fields of satellite-derived surface wind computed with the logarithmic wind law agree well with fields of observed surface wind in most regions. Magnitudes of the standard deviation of the difference in surface wind speed range from approximately 2 to 4 m/s, and satellite-derived surface winds are able to depict flow across a cold front and around a low-pressure center.

Download or read book A Comparison of Numerically Determined Divergent and Non divergent Winds to Geostrophic Winds written by Fred Ernst Lacey and published by . This book was released on 1964 with total page 64 pages. Available in PDF, EPUB and Kindle. Book excerpt: Numerical weather analysis relies heavily on numerically computed winds both for direct output and internally for calculating advection and other purposes. It is the intent of this paper to compute, analyze, and compare the geostrophic, the non-divergent, the divergent, and a combination of the latter two. Where there occurs a significant difference between these numerically derived winds, an attempt is made to compare each to the observed winds. This study is made for all standard levels through 300 mb. Data and several computer programs were furnished by the U.S. Navy Fleet Numerical Weather Facility, Monterey, California. (Author).

Download or read book Atmospheric Rivers written by F. Martin Ralph and published by Springer Nature. This book was released on 2020-07-10 with total page 284 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book is the standard reference based on roughly 20 years of research on atmospheric rivers, emphasizing progress made on key research and applications questions and remaining knowledge gaps. The book presents the history of atmospheric-rivers research, the current state of scientific knowledge, tools, and policy-relevant (science-informed) problems that lend themselves to real-world application of the research—and how the topic fits into larger national and global contexts. This book is written by a global team of authors who have conducted and published the majority of critical research on atmospheric rivers over the past years. The book is intended to benefit practitioners in the fields of meteorology, hydrology and related disciplines, including students as well as senior researchers.
