Robustness of future atmospheric circulation changes over the EURO-CORDEX domain

European climate is associated with variability and changes in the mid-latitude atmospheric circulation. In this study, we aim to investigate potential future change in circulation over Europe by using the EURO-CORDEX regional climate projections at 0.11° grid mesh. In particular, we analyze future change in 500-hPa geopotential height (Gph), 500-hPa wind speed and mean sea level pressure (MSLP) addressing different warming levels of 1 °C, 2 °C and 3 °C, respectively. Simple scaling with the global mean temperature change is applied to the regional climate projections for monthly mean 500-hPa Gph and 500-hPa wind speed. Results from the ensemble mean of individual models show a robust increase in 500-hPa Gph and MSLP in winter over Mediterranean and Central Europe, indicating an intensification of anticyclonic circulation. This circulation change emerges robustly in most simulations within the coming decade. There are also enhanced westerlies which transport warm and moist air to the Mediterranean and Central Europe in winter and spring. It is also clear that, models showing different responses to circulation depend very much on the global climate model ensemble member in which they are nested. For all seasons, particularly autumn, the ensemble mean is much more correlated with the end of the century than most of the individual models. In general, the emergence of a scaled pattern appears rather quickly.Tugba Ozturk was supported by the Scientific and Technological Research Council of Turkey (TUBITAK) under the programme TUBITAK 2219—International Postdoctoral Research Fellowship.

Projected changes in extreme temperature and precipitation indices over CORDEX-MENA domain

In this study, projected changes in climate extreme indices defined by the Expert Team on Climate Change Detection and Indices were investigated over Middle East and North Africa. Changes in the daily maximum and minimum temperature-and precipitation-based extreme indices were analyzed for the end of the 21st century compared to the reference period 1971–2000 using regional climate model simulations. Regional climate model, RegCM4.4 was used to downscale two different global climate model outputs to 50 km resolution under RCP4.5 and RCP8.5 scenarios. Results generally indicate an intensification of temperature-and precipitation-based extreme indices with increasing radiative forcing. In particular, an increase in annual minimum of daily minimum temperatures is more pronounced over the northern part of Mediterranean Basin and tropics. High increase in warm nights and warm spell duration all over the region with a pronounced increase in tropics are projected for the period of 2071–2100 together with decrease or no change in cold extremes. According to the results, a decrease in total wet-day precipitation and increase in dry spells are expected for the end of the century.Publisher's Versio

Investigation of spectroscopic properties with computational chemistry method of Zinc(II)–Sulfatiazole-Diethylenetriamine Complex: Molecular modeling study

Işını kırınım deneyi ve spektroskopik özellikleri incelenen yapının kuramsal hesaplamaları DFT, B3LYP ve LanL2DZ baz seti kullanılarak hesaplanmıştır. Optimize yapının ve X-ışını kırınımı sonucunda elde dilen deneysel yapının geometrik parametreleri oldukça uyumludur. Sulfatiyazol ligantı ise DFT/B3LYP/6-311G baz seti kullanılarak hesaplanmıştır. Kompleksin en kararlı hali elde edildikten sonra HOMO ve LUMO enerjilerinden lokal ve global kimyasal aktiviteleri belirlenmiştir. Moleküller arası etkileşimlerin % katkısı, parmak izi tayini ve toplam yüzey haritaları Hirshfeld yüzey analizi yöntemi ile incelenmiştir. Öncü moleküler orbitaller olan HOMO ve LUMO enerjileri kullanılarak hesaplanan sertlik ve yumuşaklık parametreleri ile global kimyasal aktiviteleri belirlenmiştir ve Mulliken popülasyon analizi ve moleküler elektrostatik potansiyel ile lokal kimyasal aktivite verileri elde edilmiştir. Böylece yapının elektrofilik ve nükleofilik indeksi belirlenmektedir. Ayrıca daha önce Öztürk tarafından sentezlenen Zn-stz komleksin teorik IR değerleri deneysel sonuçları ile karşılaştırılmıştır.The theoretical calculations of the structure, whose X-ray diffraction experiment and spectroscopic properties were examined, were calculated using the DFT, B3LYP and LanL2DZ base set. The geometric parameters of the optimized structure and the experimental structure obtained as a result of X-ray diffraction are quite compatible. Sulfatiazole ligand was calculated using the DFT / B3LYP / 6-311G base set. After obtaining the most stable form of the complex, local and global chemical activities were determined from HOMO and LUMO energies. % contribution of intermolecular interactions, fingerprint determination and total surface maps were examined by Hirshfeld surface analysis method. Global chemical activities have been determined with the hardness and softness parameters calculated using the leading molecular orbitals, HOMO and LUMO energies, and local chemical activity data has been obtained with Mulliken population analysis and molecular electrostatic potential. Thus, the electrophilic and nucleophilic index of the structure is determined. In addition, the theoretical IR values of the Zn-stz complex synthesized by Öztürk were compared with the experimental results

The effect of body mass index on traditional 226 Hz tympanometry and wideband tympanometry test results

Objectives: The aim of this study was to investigate the possible effects of body mass index (BMI) on traditional 226 Hz tympanometry and wideband tympanometry (WBT) to gain a better understanding of resonance frequency. Patients and Methods: A total of 158 ears of 79 volunteers (19 males, 60 females; mean age: 20.5 years; range, 18 to 27 years) who had normal hearing and normal otoscopic examination findings were included in the study between October 2019 and June 2020. By measuring the weight and height of the participants, their BMI values were classified into three groups: ≤18.5 kg/m2 (underweight), 18.5 to 24.9 kg/m2 (normal weight), and ≥25.0 kg/m2 (overweight). Tympanometric evaluations were conducted using the Interacoustics-Titan WBT. Results: The difference of ear canal volume (ECV) was significant between the two sexes (p<0.05), while there was no significant difference in the tympanometric peak pressure, compliance, gradient, and resonance frequency between the sexes (p>0.05). A significant difference was found in the ECV and resonance frequency among the three BMI groups (p<0.05). Accordingly, as the BMI increased, the ECV increased and the resonance frequency decreased (p<0.05). Conclusion: The BMI may affect ECV and resonance frequency values which should be considered during the examination

Impact of climate change on natural snow reliability, snowmaking capacities, and wind conditions of ski Resorts in Northeast Turkey: a dynamical downscaling approach

Many ski resorts worldwide are going through deteriorating snow cover conditions due to anthropogenic warming trends. As the natural and the artificially supported, i.e., technical, snow reliability of ski resorts diminish, the industry approaches a deadlock. For this reason, impact assessment studies have become vital for understanding vulnerability of ski tourism. This study considers three resorts at one of the rapidly emerging ski destinations, Northeast Turkey, for snow reliability analyses. Initially one global circulation model is dynamically downscaled by using the regional climate model RegCM4.4 for 1971-2000 and 2021-2050 periods along the RCP4.5 greenhouse gas concentration pathway. Next, the projected climate outputs are converted into indicators of natural snow reliability, snowmaking capacity, and wind conditions. The results show an overall decline in the frequencies of naturally snow reliable days and snowmaking capacities between the two periods. Despite the decrease, only the lower altitudes of one ski resort would face the risk of losing natural snow reliability and snowmaking could still compensate for forming the base layer before the critical New Year's week. On the other hand, adverse high wind conditions improve as to reduce the number of lift closure days at all resorts. Overall, this particular region seems to be relatively resilient against climate change.Publisher's Versio

Analysing projected changes in future air temperature and precipitation climatology of Turkey by using RegCM4.3.5 climate simulations
