Meteorology is a branch of the atmospheric sciences that is concerned with weather forecasting. The different variables of the Earth's atmosphere such as temperature, air pressure, water vapor and mass flow are subject to change with time and their interactions with each other. These changes contribute to variations in the weather. The quantities of temperature, pressure, humidity and wind are measured by using the thermometer, barometer, hygrometer and the anemometer. Air quality sensors for analyzing carbon monoxide, methane, carbon dioxide, ozone, dust or smoke in the air are also widely used. Flood sensor, rain gauge, seismometer, lightning sensor, etc. are other instruments that are crucial for gathering meteorological data. The applications of meteorology are in agriculture, military, energy production, transport and construction. This book is a compilation of chapters that discuss the most vital concepts and emerging trends in the field of meteorology. It aims to shed light on some of the unexplored aspects and the recent researches in this field. It is a collective contribution of a renowned group of international experts. Those in search of information to further their knowledge will be greatly assisted by this book.
