Available in PDF, EPUB and Kindle. Book excerpt: The problem of electrical charges on raindrops from non-thunderstorm clouds is investigated. Measurements of raindrop charges, precipitation currents and space charges made in various parts of the world indicate that on the average positive charges prevail on raindrops. To explain rain charges, a well known hypothesis requires the melting of snow. In Hawaii, however, rain often forms by condensation and coalescence without ice or snow in the upper portions of the cloud. Yet raindrop charges do not differ from charges measured in other types of rain. Measurements of charges on Hawaiian rain are discussed together with observations of electrical field and condensation nuclei profiles. It was found that positive charges are of the order of 10−4 esu. A correlation of these charges with wind speed was found. Electric fields in rain clouds are generally positive except at the lower cloud boundary where negative fields of up to -1000 V/m exist. Several thunderstorm theories are discussed and their applicability to the warm mechanism is examined. A new hypothesis is necessary to explain the observed electrical features of warm rain. A theory based on influence is presented and formulated. Due to low electrical conductivity inside the cloud, positive space charges form in the upper part of the cloud and negative in the lower, influenced by an impressed conduction current from above the cloud. These space charges diffuse to the raindrops. Considering a coalescence mechanism for drop growth, the residence time of raindrops in the negative space charge area is much smaller than the corresponding time in the positive area, and so the drops usually leave the cloud with a positive charge. Numerical solutions to drop charges and electric field profiles using a realistic cloud model were obtained through the use of digital computer techniques. The theoretical results for charges on raindrops and electric field patterns agree well with observations.

Download or read book Storm and Cloud Dynamics written by William R. Cotton and published by Academic Press. This book was released on 2010-12-21 with total page 826 pages. Available in PDF, EPUB and Kindle. Book excerpt: Storm and Cloud Dynamics focuses on the dynamics of clouds and of precipitating mesoscale meteorological systems. Clouds and precipitating mesoscale systems represent some of the most important and scientifically exciting weather systems in the world. These are the systems that produce torrential rains, severe winds including downburst and tornadoes, hail, thunder and lightning, and major snow storms. Forecasting such storms represents a major challenge since they are too small to be adequately resolved by conventional observing networks and numerical prediction models. Provides a complete treatment of clouds integrating the analysis of air motions with cloud structure, microphysics, and precipitation mechanics Describes and explains the basic types of clouds and cloud systems that occur in the atmosphere-fog, stratus, stratocumulus, altocumulus, altostratus, cirrus, thunderstorms, tornadoes, waterspouts, orographically induced clouds, mesoscale convection complexes, hurricanes, fronts, and extratropical cyclones Summarizes the fundamentals, both observational and theoretical, of atmospheric dynamics, thermodynamics, cloud microphysics, and radar meteorology, allowing each type of cloud to be examined in depth Integrates the latest field observations, numerical model simulations, and theory Supplies a theoretical treatment suitable for the advanced undergraduate or graduate level, as well as post-graduate

Download or read book The Earth s Electric Field written by Michael C. Kelley and published by Newnes. This book was released on 2013-09-21 with total page 230 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Earth’s Electric Field provides you with an integrated and comprehensive picture of the generation of the terrestrial electric fields, their dynamics and how they couple/propagate through the medium. The Earth’s Electric Field provides basic principles of terrestrial electric field related topics, but also a critical summary of electric field related observations and their significance to the various related phenomena in the atmosphere. For the first time, Kelley brings together information on this topic in a coherent way, making it easy to gain a broad overview of the critical processes in an efficient way. If you conduct research in atmospheric science, physics, atmospheric chemistry, space plasma physics, and solar terrestrial physics, you will find this book to be essential reading. The only book on the physics of terrestrial electric fields and their generation mechanisms, propagation and dynamics–making it essential reading for scientists conducting research in upper atmospheric, ionospheric, magnetospheric and space weather Covers the processes related to electric field generation and electric field coupling in the upper atmosphere along with providing new insights about electric fields generated by sources from sun to mud Focuses on real-world implications—covering topics such as space weather, earthquakes, the effect on power grids, and the effect on GPS and communication devices

Book excerpt: Atmospheric Electricity, Second Edition provides a comprehensive discussion of the various aspects and areas of concern in atmospheric electricity. The book limits its concerns to the essential and unique topics that are relevant to the general problems in atmospheric electricity. The text first presents historical survey atmospheric electricity, and then proceeds to covering the general principles involved in atmospheric electricity. The subsequent chapters cover the much more specific and technical concepts, such as the separation of charge; the lightning discharge; the transfer of charge; the vertical potential gradient; and ions and nuclei. The title will be of great use to students, researchers, and practitioners of disciplines related to meteorology.

This book was released on 1996-12-31 with total page 984 pages. Available in PDF, EPUB and Kindle. Book excerpt: Cloud physics has achieved such a voluminous literature over the past few decades that a significant quantitative study of the entire field would prove unwieldy. This book concentrates on one major aspect: cloud microphysics, which involves the processes that lead to the formation of individual cloud and precipitation particles. Common practice has shown that one may distinguish among the following addi tional major aspects: cloud dynamics, which is concerned with the physics respon sible for the macroscopic features of clouds; cloud electricity, which deals with the electrical structure of clouds and the electrification processes of cloud and precipi tation particles; and cloud optics and radar meteorology, which describe the effects of electromagnetic waves interacting with clouds and precipitation. Another field intimately related to cloud physics is atmospheric chemistry, which involves the chemical composition ofthe atmosphere and the life cycle and characteristics of its gaseous and particulate constituents. In view of the natural interdependence of the various aspects of cloud physics, the subject of microphysics cannot be discussed very meaningfully out of context. Therefore, we have found it necessary to touch briefly upon a few simple and basic concepts of cloud dynamics and thermodynamics, and to provide an account of the major characteristics of atmospheric aerosol particles. We have also included a separate chapter on some of the effects of electric fields and charges on the precipitation-forming processes.
