Book Synopsis Physics and Chemistry of Clouds by : Dennis Lamb
Download or read book Physics and Chemistry of Clouds written by Dennis Lamb and published by Cambridge University Press. This book was released on 2011-04-28 with total page 599 pages. Available in PDF, EPUB and Kindle. Book excerpt: Clouds affect our daily weather and play key roles in the global climate. Through their ability to precipitate, clouds provide virtually all of the fresh water on Earth and are a crucial link in the hydrologic cycle. With ever-increasing importance being placed on quantifiable predictions - from forecasting the local weather to anticipating climate change - we must understand how clouds operate in the real atmosphere, where interactions with natural and anthropogenic pollutants are common. This textbook provides students - whether seasoned or new to the atmospheric sciences - with a quantitative yet approachable path to learning the inner workings of clouds. Developed over many years of the authors' teaching at Pennsylvania State University, Physics and Chemistry of Clouds is an invaluable textbook for advanced students in atmospheric science, meteorology, environmental sciences/engineering and atmospheric chemistry. It is also a very useful reference text for researchers and professionals.

This book was released on 1974 with total page 120 pages. Available in PDF, EPUB and Kindle. Book excerpt: "A numerical model has been developed to simulate the growth of cloud droplets by condensation upon a spectrum of hygroscopic nuclei. The model is applicable to cloud simulation chamber conditions as well as to the study of the role of these nuclei on cloud base microstructure. Equations are given for the growth by condensation of water vapor on a population of hygroscopic nuclei in a volume being cooled by expansion. The equations are integrated simultaneously, using Hamming's modified predictor-corrector method for given initial conditions, to obtain the droplet size distribution, temperature, pressure, supersaturation, and liquid water content. Temperature fluctuations, sedimentation of droplets, seeding with hygroscopic nuclei, and the effect of surface films in retarding the growth of nuclei are also considered. By assuming homogeneous thermodynamic parameters and condensation nuclei distribution in the initial volume, the results for adiabatic expansion show a tendency for the droplet spectrum to narrow, similar to the results obtained for closed parcel models. Temperature fluctuations tend to broaden the spectrum. This broadening depends upon the amplitude, frequency of fluctuations, and the expansion rate of the volume. Sedimentation of droplets is shown to be a critical factor in limiting the rate of expansion and the time required to record reliable observations. Calculations on the effect of seeding nuclei after a certain time of spectrum development indicate that the seeding effect depends significantly on the concentration and size of nuclei inserted, and the time of insertion. The passivation of nuclei by surfactant shows that surface films, in general, serve to delay the formation of cloud droplets for a time, depending upon the initial film thickness, condensation coefficient, size spectrum distribution of the nuclei, and the cooling rate"--Abstract, leaves iii-iv.

This book was released on 2023 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Abstract : Atmospheric clouds are crucial to weather and climate, and the rate at which droplets collide and coalesce to form precipitation is one of the fundamental controlling processes. The convection-cloud chamber allows the interactions between aerosols and cloud droplets produced by condensation to be investigated within a turbulent environment. Studying the full range of microphysical conditions in atmospheric clouds is not possible, however, unless conditions for droplet growth by collision and coalescence are also achieved. In this study, we explore the conditions favorable to collision-coalescence growth in convection-cloud chambers, extending previous work on steady-state droplet size distributions due to condensation alone. We obtain analytic expressions for cloud droplet collision-coalescence rates, and for the functional form of droplet size distributions themselves. We derive several scaling laws and demonstrate consistency between these theoretical results and Monte-Carlo simulations of growth and precipitation within a convection-cloud chamber. Finally, we gain insights into the role of external parameters such as injection rate, supersaturation forcing, and chamber height in controlling the strength of the collision-coalescence process, and the resulting shape of the droplet size distribution.

This book was released on 2018 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Abstract : In this study, we attempt to perform in-cloud measurements, both in the laboratory using the Michigan Tech $\Pi$-chamber and in the atmosphere via the CSET field campaign. Atmospheric turbulence is believed to play a critical role in the growth, development and dissipation of clouds and it is important to study its effect in order to better understand and predict cloud properties such as albedo and lifetime. We use digital in-line holography to measure the effect of turbulence on cloud microphysical properties such as variations in droplet number concentration and droplet or ice particle size. In the first half, we study warm clouds and investigate how cloud droplets grow between the regimes dominated by diffusional growth and growth by collision-coalescence. We propose that microphysical variability in droplet number concentration will lead to local increase in supersaturation fluctuations. Prior stochastic condensation theory assumed constant cloud properties such as phase relaxation time. We create a steady state warm turbulent mixing cloud in the laboratory and use digital in-line holography to obtain local instantaneous droplet number concentrations. We show using these measurements that phase relaxation time distributions are considerably broad leading to additional increase in droplet spectral width. We then compare these results with in-situ measurements of marine stratocumulus clouds during the CSET campaign. We find certain signatures which we define as microphysical fingerprints of stochastic condensation occurring in these clouds. In the second half, we focus our attention on mixed phase clouds which are ubiquitous in the atmosphere but very difficult to measure. By creating steady state mixed phase clouds in the laboratory, using digital in-line holography, we were able to measure cloud droplet and ice particle properties for extended period of time. We show that cloud glaciation is a function of the steady state supersaturation and can be altered by varying the ratio between ice nuclei and cloud condensation nuclei. By varying this ratio, we were able to generate steady state mixed phase clouds with varying ice fraction and study their properties.
