Life on Earth is critically dependent upon the continuous cycling of water between oceans, continents and the atmosphere. Precipitation (including rain, snow, and hail) is the primary mechanism for transporting water from the atmosphere back to the Earth’s surface. It is also the key physical process that links aspects of climate, weather, and the global hydrological cycle. Changes in precipitation regimes and the frequency of extreme weather events, such as floods, droughts, severe ice/snow storms, monsoon fluctuations and hurricanes are of great potential importance to life on the planet. One of the factors that could contribute to precipitation modification is aerosol pollution from various sources such as urban air pollution and biomass burning. Natural and anthropogenic changes in atmospheric aerosols might have important implications for precipitation by influencing the hydrological cycle, which in turn could feed back to climate changes. From an Earth Science perspective, a key question is how changes expected in climate will translate into changes in the hydrological cycle, and what trends may be expected in the future. We require a much better understanding and hence predictive capability of the moisture and energy storages and exchanges among the Earth’s atmosphere, oceans, continents and biological systems. This book is a review of our knowledge of the relationship between aerosols and precipitation reaching the Earth's surface and it includes a list of recommendations that could help to advance our knowledge in this area.

Are your counters covered with appliances you had to have but rarely use? Are your cupboards stuffed with clothes that you hope to fit back into or that you paid a fortune for but only wore once? Have you been hanging on to that hideous teapot your mother gave you 10 years ago only because she gave it to you? Every time you go shopping do you come back with bags of more stuff because that pillow/blouse/cd/mixer will be the one thing that changes your life and then it doesn't change your life because you have nowhere to put it? In It's All Too Much,organisational guru Peter Walsh challenges you to answer a very simple but scary question: Does the stuff you own contribute to the life you hope to achieve or does it get in the way of your vision? Peter helps you assess the state of your home without any sugar coating and will teach you how to confront and conquer the stuff that is holding you back by identifying the purpose of each and every object in your home and assessing your reasons for holding onto it. He shows you how to identify which room is the heart of your home and then shows you why it is so important to keep that space clean and clear of clutter - if the heart of your home is clogged what does that say about you? He then helps you go room by room to ask the important questions: What is the room? What's its purpose? What is this item? Does it contribute positively to the life you want? The answers to these questions will help you understand your priorities and fix your relationship with your stuff. And in gaining this understanding you can start to clear out the clutter!

The studies in this dissertation aim at advancing our scientific understandings about physical processes involved in the aerosol-cloud-precipitation interaction and quantitatively assessing the impacts of aerosols on the cloud systems with diverse scales over the globe on the basis of the observational data analysis and various modeling studies. As recognized in the Fifth Assessment Report by the Inter-government Panel on Climate Change, the magnitude of radiative forcing by atmospheric aerosols is highly uncertain, representing the largest uncertainty in projections of future climate by anthropogenic activities. By using a newly implemented cloud microphysical scheme in the cloud-resolving model, the thesis assesses aerosol-cloud interaction for distinct weather systems, ranging from individual cumulus to mesoscale convective systems. This thesis also introduces a novel hierarchical modeling approach that solves a long outstanding mismatch between simulations by regional weather models and global climate models in the climate modeling community. More importantly, the thesis provides key scientific solutions to several challenging questions in climate science, including the global impacts of the Asian pollution. As scientists wrestle with the complexities of climate change in response to varied anthropogenic forcing, perhaps no problem is more challenging than the understanding of the impacts of atmospheric aerosols from air pollution on clouds and the global circulation.

The "European Experiment on the Transport and Transformation of Environmentally Relevant Trace Constituents over Europe" (EUROTRAC) was established in 1986 to tackle the scientific problem and combine the expertise, knowledge and resources in Europe, in order to apply them over a large region covering the greater part of the continent. EUROTRAC is a coordinated multidisciplinary scientific research project involving field measurements, laboratory studies, instrument development and development of comprehensive computer models for the simulation of the physical and chemical processes in the lower atmosphere.

Topics in Current Aerosol Research, Part 2 contains some selected articles in the field of aerosol study. The chosen topics deal extensively with the theory of diffusiophoresis and thermophoresis. Also covered in the book is the mathematical treatment of integrodifferential equations originating from the theory of aerosol coagulation. The book is the third volume of the series entitled International Reviews in Aerosol Physics and Chemistry. The text offers significant understanding of the methods employed to develop a theory for thermophoretic and diffusiophoretic forces acting on spheres in the range from free molecules to continuum behavior. It explores the mathematical solution for the kinetic model of the coagulation equation. Another topic of interest is the means to estimate size dispersal function for clouds of particles undergoing collision. The text can be a useful tool for practicing scientists and graduate students in physics, meteorology, geophysics, physical chemistry, environmental science, medicine, chemical engineering, and aerospace engineering.

The selection and design of aerosol removal equipment depend largely on knowledge of the size of the particle. In this work the distribution of particle sizes of aerosols of sulfuric, phosphoric, hydrochloric, hydrobromic, chlorosulfonic, and nitric acids was measured by means of a four-stage, high velocity jet impactor. The effect of the relative humidity of the air system, the addition of foreign nuclei, the concentration of the aerosol particles and time on the size distribution was studied.
