Trends and changes in tropical and summer days at the Adana Sub-Region of the Mediterranean Region, Southern Turkey

Changes in Summer and Tropical Days at the Lakes District of the Mediterranean Region of Turkey Between the Period of 1969-2014

“…Accordingly, the annual number of summer and tropical days has increased in general (in all stations between the period of 1980-1989 and 2000-2009) although it changes according to the periods at the Lakes District of Turkey varied (Figure 3). This result coincides with the result of the research conducted by IPCC (2013) that the number of summer days increased in parallel with the increase in air temperatures on a global scale (Aykır, 2017); with the result of the research conducted by Erlat and Yavaşlı (2011) that the annual summer and tropical day numbers has increased in the southern regions of the European continent during the last 30 years; with the result of the research conducted by Erlat and Türkeş (2013) that after the summer of 1975 as well as an overall upward trend in the annual number of summer days and tropical days; with the result of the research conducted by Erlat and Yavaşlı (2009) that there is an upward trend in the annual number of summer and tropical days in Aegean Region; with the result of the research conducted by Altın and Barak (2017) that the annual number of summer and tropical days shows positive anomaly values in Adana during 1993-2014; with the result of the research conducted by Kılıç (2016) that there is a statistically significant upward trend in the number of the annual total summer and tropical days in Beyşehir and Seydişehir during the period of 1972-2011.…”

“…A study covering the 1939-2008 period also noted a significant increase in the annual number of summer and tropical days in the Aegean Region (Erlat and Yavaşlı, 2011). In a study covering the Adana Sub-Region, which is also close to the study area, it was determined that the annual number of summer and tropical days showed positive anomaly values between 1993(Bayer Altın and Barak, 2017. In a study covering Beyşehir and Seydişehir stations included in the scope of this study, the total annual number of summer and tropical days in these two stations as of 1972-2011 period significant level increase trend has been identified (Kılıç, 2016).…”

“…Research on the Mediterranean basin on this subject can be given as examples of the research of Arseni-Papadimitriou and Maheras (1991), Xoplaki et al (2003), Kostopoulou and Jones (2005), Diffenbaugh et al (2007), Alpert et al (2008), Giorgi and Lionello (2008), Hertig et al (2010), Kuglitsch et al (2010), Simolo et al (2014). Research on Turkey on the change in air temperatures and climate can be given as examples of the research of Türkeş (1995), Türkeş et al (1995), Türkeş et al (1996), Kadıoğlu (1997), Çiçek (2000), Kadioğlu et al (2001), Türkeş et al (2002), Türkeş and Sümer (2004); Acar Deniz and Türkeş (2011), Toros (2012), Karabulut (2012), Acar Deniz (2013), Acar Deniz and Gönençgil (2015), Dogan et al (2015), Sütgibi (2015), Gönençgil and Acar Deniz (2016) and Bayer Altın and Barak (2017).…”

A determination of season shifting across Turkey in the period 1965–2020

“…For future projections from 2071 to 2100, an increase of 1°C in summer temperatures is expected in the spring and autumn seasons in this region (Türkeş, 2012). Many studies have indicated the increase in the average and extreme temperatures over Turkey and/or the eastern Mediterranean (Arseni‐Papadimitriou and Maheras, 1991; Kadıoğlu, 1997; Kadıoğlu et al ., 2001; Türkeş et al ., 2002; Xoplaki et al ., 2003; Türkeş and Sumer, 2004; Kostopoulou and Jones, 2005; Diffenbaugh et al ., 2007; Alpert et al ., 2008; Giorgi and Lionello, 2008; Hertig et al ., 2010; Kuglitsch et al ., 2010; Acar Deniz and Türkeş, 2011; Karabulut, 2012; Toros, 2012; Acar Deniz, 2013; Simolo et al ., 2014; Acar Deniz and Gonencgil, 2015; Bayer Altın and Barak, 2017; Aksu, 2021). Climate modelling studies have indicated that warming is expected to continue at a higher rate in the Mediterranean Basin until the end of the twenty‐first century (Mariotti et al ., 2015).…”

“…The number of summer and tropical days is also reported to be increasing in Turkey, the eastern Mediterranean and in Europe in the last three decades (Erlat and Yavaşlı, 2009; Giannakopoulos et al ., 2009; Acar Deniz, 2013; Erlat and Türkeş, 2013; Aykır, 2017; Bayer Altın and Barak, 2017; Güçlü, 2020). Erlat and Türkeş (2016) studied 80 climatological stations in Turkey and found that the first autumn frost is observed later, while the last spring frost is earlier.…”
