Über dieses Buch

Lectures in Meteorology is a comprehensive reference book for meteorologists and environmental scientists to look up material on the thermodynamics, dynamics and chemistry of the troposphere. The lectures demonstrate how to derive/develop equations – an essential tool for model development. All chapters present applications of the material including numerical models. The lectures are written in modular form, i.e. they can be used at the undergraduate level for classes covered by the chapters or at the graduate level as a comprehensive, intensive course. The student/instructor can address chapters 2 (thermodynamics) and 4 (radiation) in any order. They can also switch the order of chapter 5 (chemistry) and 6 (dynamics). Chapter 7 (climatology and climate) requires an understanding of all chapters. Chapter 3 (cloud physics) needs basics from chapter 2 to understand the cloud microphysical processes. The governing conservation equations for trace constituents, dry air, water substances, total mass, energy, entropy and momentum are presented, including simplifications and their application in models. A brief introduction to atmospheric boundary layer processes is presented as well. Basic principles of climatology discussed include analysis methods, atmospheric waves and their analytical solutions, tropical and extra-tropical cyclones, classical and non-classical mesoscale circulations, and the global circulation. The atmospheric chemistry section encompasses photolytic and gas-phase processes, aqueous chemistry, aerosol processes, fundamentals of biogeochemical cycles and the ozone layer. Solar and terrestrial radiation; major absorber; radiation balance; radiative equilibrium; radiative-convective equilibrium; and basics of molecular, aerosol and cloud adsorption and scattering and their use in remote sensing are also presented.

Chapter 1. Introduction
Abstract
This chapter defines various sub-disciplines within meteorology. It gives a motivation why humans were interested in meteorology. It provides a brief history of the development of meteorology, and illustrates how other disciplines affected the progress in meteorology. It discusses the vertical structure of the atmosphere under different aspects (temperature, pressure, composition, magnetism, ionization).

Chapter 2. Thermodynamics
Abstract
This chapter provides the fundamentals of the thermodynamics of irreversible processes as they are used in meteorology. The discussion includes the laws of thermodynamics, kinetic gas theory, atmospheric stability, and thermodynamics charts. The idea of an air parcel and various thermodynamic systems as they are used in meteorology and climate modeling are introduced as well. Both adiabatic and diabatic processes are discussed. Thermodynamic potentials are introduced for explanation of thermodynamical, dynamical and chemical concepts throughout the book. The chapter covers dry and moist air, phase transition processes and genesis of air masses. In addition, various meteorological concepts important for atmospheric modeling, weather forecasting and analysis of meteorological measurements like the potential temperature, hydrostatic approximation, convective inhibition, convective available potential energy are presented.

Chapter 3. Clouds and Precipitation
Abstract
This chapter introduces the theoretical basis of the seven microphysical processes and the terms of their sub-processes. It discusses the concepts of conservation of total water mass, as well as bulk-parameterizations and spectral cloud models. The various cloud types and cloud morphology as a result of their microphysical properties and formation processes are presented as well. Furthermore, links to applications in remote sensing, and links to the role of clouds in atmospheric chemistry are given.

Chapter 4. Atmospheric Radiation
Abstract
This chapter covers the nomenclature and basic quantities used in meteorology to describe the atmospheric radiation processes. The principle of blackbody radiation, shortwave and long-wave radiation are applied to the atmosphere. The basics of the interaction radiation-atmosphere and the radiative transfer are presented. The radiative transfer equation including the solution for a plane-parallel non-scattering atmosphere are discussed. Finally the concepts are applied to the global radiation and surface energy budgets and discussed in view of climate. The chapter also covers remote sensing applications from satellites and the greenhouse effect.

Chapter 5. Atmospheric Chemistry
Abstract
Since the industrial revolution, the anthropogenic emissions of various trace species changed the composition of the atmosphere appreciably. This chapter presents the basics of atmospheric chemistry of the polluted and unpolluted atmosphere including some basic modeling concepts. The sources, transformation in the gas phase and aqueous phase, gas-to-particle conversion, aerosol physics and chemistry, transport, and removal of atmospheric trace gases as well as their relation to atmospheric physics and biogeochemical cycles are discussed and the relations of air chemistry to thermodynamics, radiation and cloud physics are elucidated.

Chapter 6. Dynamics and Synoptic
Abstract
In the chapter Dynamics, and Synoptic, the basic laws for describing the kinematic and dynamic behavior of tropospheric flows are presented and discussed. The conservation equations for momentum (Newton’s 2nd law), total mass (equation of continuity), dry air, water substances, trace constituents, and energy (1st principle of thermodynamics) are presented and explained, where inertial frames and moving frames rotating with the Earth are considered. This presentation includes different kinds of coordinate systems. Simplifications like the hydrostatic and geostrophic approximations are related to scaling considerations (scale analysis). Balanced curved flows, streamlines and trajectories are explained as well. Circulation and vorticity principles are discussed to analyze rotational flows. This part includes, for instance, the balance equation for vorticity and the distinction between absolute and relative vorticity. Wave analysis is explained by examples like gravity waves and Rossby waves. Principles of Ekman’s physics of the atmospheric boundary layer (ABL) are presented to point out the effects of turbulent motion. The chapter also encompasses how principles of dynamics and kinetic as well as numerical weather prediction model results are used in weather forecasting.

Chapter 7. Climate and Climatology
Abstract
This chapter is a brief introduction to climate and climatology in a sense as it is used in meteorology. It introduces the basic nomenclature used in climate studies and climatology. The chapter provides a brief introduction into basic climate statistics and climate analysis methods and discusses the general circulation in terms of examples of applications. Major large scale and mesoscale features are elucidated from a meteorological point of view as they are part of the regional climate. Furthermore, a brief glimpse on the biogeophysical cycle is provided. Major challenges of climate and Earth system modeling as well as regional climate modeling are pointed out. The chapter also presents the Köppen-Geiger classification that is recently often applied for climate assessment and assessment of climate model simulations.
