Special Issue Information

Dear Colleagues,

Climate change is a mounting stress on human societies and natural systems, and its influence on the hydrological cycle is unneglectable. Rising global temperature leads to an increased evaporation rate, speeding up parts of the water cycle with more precipitation and even increasing the likelihood of coastal flooding. However, enhanced evaporation can reduce surface water and contribute to drought. Human-caused climate change can foster changes in the location, frequency, and intensity of hydroclimate extremes. To facilitate emergency response and mitigate socio-economic loss, it is necessary to advance the current understanding of the mechanisms and processes that contribute to the impacts of climate change on hydrologic variables, such as precipitation, moisture transport, and soil moisture. This Special Issue focuses on climate change impacts on the hydrological cycle, including hydrometeorological interaction and hydroclimate extremes. Potential submissions include, but are not limited to, observational analysis; mechanisms and processes study; the assessment of projection uncertainties; the assessment of regional and spatial dependencies; and approaches to quantify the future changes in hydroclimate extremes.

Global climate change has emerged as a problem in recent years, and its effects will likely continue to increase in the future. Several scientific studies conducted in the Mediterranean region have demonstrated relatively stationary trends for annual precipitation and significant upward trends for mean annual temperature. These trends present several implications, especially in the Greek islands that serve as major summer tourist destinations where the population is already unable to meet their water demands. The aim of this study is to investigate both long- and short-term variations in temperature and precipitation on three Greek islands in the Mediterranean Sea (Mykonos, Naxos, and Kos). The temperature and rainfall trends, as well as their magnitudes at yearly, seasonal, and monthly time steps, were determined using the non-parametric Mann–Kendall trend test. The Standardized Precipitation Index (SPI) was employed to identify the drought periods. According to the results, precipitation slightly increased (almost stationary) in the three islands, although this rise was not statistically significant. All three islands experienced a sharp and statistically significant increase in their mean annual air temperatures. The region may experience drought episodes as a result of the high temperature increase, which would drastically reduce the amount of water, available for use due to the increased evapotranspiration. For the Mediterranean region, the necessity for a drought management strategy to stop or diminish the severity of drought episodes and their effects has grown into a matter of great concern. It is crucial to take measures and conduct relevant research in order to create the conditions for adaptation and mitigation of climate change consequences and the increased appearance of drought phenomena.
