Climate is the fixed or slightly varying pattern of weather of an area prevailing over a period of time. Climatology attempts to explain the impact of climatic conditions, to assist people in planning and building infrastructure and issuing warnings about potential dangers. Paleoclimatology, historical climatology, and paleotempestology are the different approaches used for determining the past and future global climatic patterns. Since climates are dynamic and complex, they are difficult to deal with. Constant in-depth research and efforts are required on the part of climatologists to deal with these frequently varying patterns. This book presents the research and studies performed by experts across the globe. It strives to provide a fair idea about this discipline and to help develop a better understanding of the latest advances within this field. It will provide comprehensive knowledge to the readers. This text will benefit climatologists, environmentalists, atmospheric scientists, professional and students alike.
