Water is central to life and determines our peaceful existence. However, extreme climate events including drought can impact the quality and quantity of water resources available for human activities. Throughout the world, water resource managers are confronted with water distribution decisions and management planning because of drought. With the ongoing global climate warming, the impact of this event on humans and their dependencies – water, agriculture, energy security, and economy – will exacerbate in the future.
Spatio-temporal characteristics of drought are strongly modulated by the large-scale atmospheric features. However, changes in the large-scale features and how they interact to induce drought events are not fully known. This is ongoing research among the climate community using both the observational data and the stat-of-the-art Earth system models. Global climate models are useful tools to study drought events, but their usability depends on how well they can represent the large-scale atmospheric variables that induce drought.
My work focuses on understanding/identifying large-scale features associated with extreme climate events. In this talk, I will present some observational results of drought analyses over the Upper Colorado River basin, Colorado USA. Also, I will talk about the performance of the Met Office Hadley Centre Global Environment Model in simulating the observed drought mechanisms over the State of Sao Paulo, Brazil.
Yomi is a meteorologist by training and has worked in many different capacities. He worked in the Aviation industry in Nigeria as a forecaster, at the Federal University of Technology Akure, Nigeria as a lecturer, and at Iowa State University as a graduate student and a teaching assistant, with full engagement in climate science research. He also worked as a postdoctoral research associate at the University of Edinburgh, UK and now as a research fellow at the University of Exeter, UK. He has passion for climate science because of the impact of extreme climate events on human being. His research focuses on understanding and characterizing changes in weather and climate extremes and associated atmospheric dynamics, thus providing decision-making tools.
