Abstract

This study examines long-term sea level changes and their relationship with meteorological parameters at the Antalya, Bodrum, Erdek, and Menteş tide gauge (TG) stations along the Mediterranean, Aegean, and Marmara coasts of Türkiye between 1985 and 2024. Sea level trends were compared using both local TG data (TUDES) and satellite altimetry data from the Copernicus Marine Service (CMEMS). Trends in meteorological parameters were evaluated using parametric (least squares linear model) and non-parametric (Mann-Kendall trend test and Sen's Slope method) statistical analyses.

The results indicate that the regional sea level rise rate for the period 1993–2024 was estimated at 3.3 ± 1.0 mm/yr based on TG data and 3.8 ± 0.7 mm/yr based on CMEMS data. Significant increases were observed in sea water temperature (0.035–0.051 °C/year) and air temperature (0.037–0.060 °C/year), while a statistically significant increase in water vapor pressure was only observed in Bodrum.

Decreases were detected in atmospheric pressure and relative humidity; however, only the decline in relative humidity at Antalya was statistically significant. Autocorrelation analysis revealed periodic trends in sea level and meteorological observations, and cross-correlation analysis identified the lagged influence of thermal expansion and atmospheric pressure variations on sea level changes.

This research is novel in employing the longest observational record for Türkiye's coastal regions, combining in-situ and satellite-based data to provide timely insights into the coastal impacts of climate change.

潮量站的长期海平面和气候变化：来自 rkiye的研究

本研究考察了1985年至2024年间土耳其地中海、爱琴海和马尔马拉海岸沿线的安塔利亚、博德鲁姆、埃尔德克和门特伊奇潮汐计站（TG）的长期海平面变化及其与气象参数的关系。利用当地TG数据（TUDES）和哥白尼海洋服务（CMEMS）的卫星测高数据比较了海平面趋势。采用参数（最小二乘线性模型）和非参数（Mann-Kendall趋势检验和Sen's斜率法）统计分析评估气象参数的趋势。结果表明，1993-2024年区域海平面上升速率基于TG数据估计为3.3±1.0 mm/yr，基于CMEMS数据估计为3.8±0.7 mm/yr。海水温度（0.035 ~ 0.051℃/年）和气温（0.037 ~ 0.060℃/年）均有显著升高，水汽压仅在博德鲁姆地区有显著升高。大气压力和相对湿度下降；然而，只有安塔利亚的相对湿度下降具有统计学意义。自相关分析揭示了海平面和气象观测的周期性变化趋势，互相关分析揭示了热膨胀和大气压力变化对海平面变化的滞后影响。这项研究的新颖之处在于，它利用了日本沿海地区最长的观测记录，结合了原位和卫星数据，及时提供了气候变化对沿海地区影响的见解。

期刊介绍： The Journal of Atmospheric and Solar-Terrestrial Physics (JASTP) is an international journal concerned with the inter-disciplinary science of the Earth''s atmospheric and space environment, especially the highly varied and highly variable physical phenomena that occur in this natural laboratory and the processes that couple them. The journal covers the physical processes operating in the troposphere, stratosphere, mesosphere, thermosphere, ionosphere, magnetosphere, the Sun, interplanetary medium, and heliosphere. Phenomena occurring in other "spheres", solar influences on climate, and supporting laboratory measurements are also considered. The journal deals especially with the coupling between the different regions. Solar flares, coronal mass ejections, and other energetic events on the Sun create interesting and important perturbations in the near-Earth space environment. The physics of such "space weather" is central to the Journal of Atmospheric and Solar-Terrestrial Physics and the journal welcomes papers that lead in the direction of a predictive understanding of the coupled system. Regarding the upper atmosphere, the subjects of aeronomy, geomagnetism and geoelectricity, auroral phenomena, radio wave propagation, and plasma instabilities, are examples within the broad field of solar-terrestrial physics which emphasise the energy exchange between the solar wind, the magnetospheric and ionospheric plasmas, and the neutral gas. In the lower atmosphere, topics covered range from mesoscale to global scale dynamics, to atmospheric electricity, lightning and its effects, and to anthropogenic changes.
