“…The results of the present study are in general agreement with the result of the available literature referred to area-averaged weather station data (Feidas et al, 2007) and in general qualitative agreement with the results of Zaifoğlu et al (2017), which are based on 37 weather stations of northern Cyprus (these authors do not provide the area-averaged data). However, the results of the present study (referred to Turkey) are in slight agreement with those of Topuz et al (2020).…”

The present study aims to examine the current trend of annual precipitation and temperature series referred to the Eastern Mediterranean basin on a national basis, including the annual variability of sea surface temperature anomalies and the connection effect with the North Atlantic Oscillation and the Mediterranean Oscillation indices (NAOI and MOI, respectively). The period under consideration is mainly the last 32 years, from 1990 to 2021. Additionally, the prediction of monthly and yearly temperature and precipitation series, based on the autoregressive integrated moving average model on a national base, for the next four or eight years, is another interesting feature of the present study. Results indicate rising trends in the annual precipitation during 1990-2021, mostly non-significant and significant warming trends in the annual temperature, including sea surface temperature. The NAOI is highly correlated mostly with annual temperature, whereas the MOI does not affect the variation of annual precipitation and temperature. The results of the present study are in general agreement with the results of available studies in the literature, and they could be of high interest to national authorities and environmental unions/organizations, to help decision-makers face climate change.

“…According to Table 5 and Figure 13, it can be seen that severe (−1.5 ≤ SPI ≤ −2) and extreme drought (SPI ≤ −2) episodes occurred in common relative periods with some variations in their characteristics. Thus, in the observation period of 1989-1991, a period of drought occurred for the entire area of Greece [8,81] as well as for the wider area of the eastern Mediterranean region [82][83][84]; the duration of the drought in Mykonos and Kos was found to be 2 months, while in Naxos it was 9 months. During the years 1999-2001, a significant drought was observed in all 3 islands with the longest duration in Mykonos (21 months), while in Naxos and Kos the duration was 8 months.…”

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.

“…For instance, the maximum daily precipitation and the frequency of heavy precipitation in Istanbul have increased significantly in the last three decades (Toros et al, 2017). Topuz et al (2020) ascribed the trends to the autumn precipitation, which is probably concerning the North Atlantic Oscillation Index.…”

Climate change can be traced in any given region by searching for changes in climatic elements' characteristics. Extreme precipitation, for example, is a characteristic of precipitation whose changes, especially in recent years, can be attributed to global warming and climate change. This study aimed to investigate possible changes in extreme precipitation in Iran by analysing the frequency of extreme rainy days duration. To this end, gridded precipitation datasets from the hydrological years 1971-1972 to 2015-2016 were used, and days associated with extreme precipitation were extracted by using thresholds of 90th, 95th, and 99th percentiles (as heavy, very heavy, and extremely heavy precipitation, respectively). Latitude and longitude showed the most significant correlation with precipitation characteristics in the spatial distribution during the study period. In addition, heavy (HP), very heavy, and extremely heavy precipitation experienced durations of 1-8, 1-7, and 1-4 days, respectively. At all extremes, the 1-day duration covered more areas and had more repetition, while the longer duration had the lowest tempo-spatial repetition. According to the results of the present study, the one-day duration of HP contributed more significantly to the annual precipitation. The proportion of this type of precipitation has been more significant in the southern and central regions of the country. Furthermore, it was revealed that the frequency of durations of short-term HP increased during the study period, whereas the duration of long-term HP declined.
