Abstract: Compound hydrometeorological extremes linked with joint occurrences of two or more essential climate variables (ECVs) affect water resources management and human health. In many regions worldwide, climate change is mainly attributed to the increased frequency and intensity of recorded extreme temperature and precipitation events; therefore, understanding their interconnection is crucial for effective forecasting and developing adaptation strategies. In the current study, in the initial phase, joint occurrences of temperature and precipitation are used to identify the concurrent or sequential occurrences of those events, specifically within the tropical and subtropical low-lying area of the State of Florida in the United States. This study evaluates temperature and precipitation data, examining their relationships through statistical methods, including trend analysis and multivariate distributions. Preliminary results indicate variations in mean joint occurrences are increasing at some study region sites requiring attention. Nonparametric tests used also confirm the changes. Non-uniform variation in joint occurrences of compound extremes in the tropical region of Florida is noted and expected to be attributed to climate variability and change along with influences from large water bodies and wetlands in the region.
