Climate studies have gained importance due to the significant effect of climate change. The extreme meteorological events can cause floods, droughts, sudden change in the temperature or change in the climate trends. Since they have an important effect on human beings and the environment, these meteorological variables should be predicted and some precautions should be taken if possible. In order to conduct any kind of statistical analysis, the nonclimatic effects should be determined and corrected or removed. Otherwise, any kind of meteorological effect should be kept to reflect the change in the variable. If there is any nonclimatic effect in the variable, the series is defined as inhomogeneous. The most important climatic variables are temperature and precipitation. The precipitation variable cannot be modeled efficiently due to its nonsymmetric shape and high variability. First, monthly total precipitation amount is simulated based on real station records. Then, in each simulation, artificial breakpoints are created and the homogeneity analysis are conducted to detect the inhomogeneity and the results are compared to decide on the best performed homogeneity test for precipitation.

Modeling of enhanced coalbed methane recovery from Amasra coalbed in Zonguldak coal basin Sınayuç, Çağlar; Gümrah, Fevzi; Department of Petroleum and Natural Gas Engineering (2007) The increased level of greenhouse gases due to human activity is the main factor for climate change. CO2 is the main constitute among these gases. Subsurface storage of CO2 in geological systems such as coal reservoirs is considered as one of the promising perspectives. Coal can be safely and effectively utilized to both store CO2 and recover CH4. By injecting CO2 into the coal beds, methane is released with CO2 adsorption in the coal matrix and this process is known as enhanced coal bed methane recovery (E...
Assessing the impact of climate change on Mogan and Eymir Lakes' levels in Central Turkey Yagbasan, Ozlem; Yazıcıgil, Hasan (2012-05-01) Global warming is likely to have significant effect on the hydrological cycle. Some parts of the world may see significant reductions in precipitation or major alterations in the timing of wet and dry seasons. Climate change is one of the serious pressures facing water resources and their management over the next few years and decades. As part of the southern belt of Mediterranean Europe, Turkey is highly vulnerable to anticipated climate change impacts. The changes in global climate will seriously affect i...
Overcoming basis risk in agricultural index insurance using crop simulation modeling and satellite crop phenology Hesamı Afshar, Mehdı; Foster, Timothy; P. Higginbottom, Thomas; Parkes, Ben; Hufkens, Koen; Mansabdar, Sanjay; Ceballos, Francisco; Kramer, Berber (2021-04-19) Extreme weather causes substantial damage to livelihoods of smallholder farmers globally and are projected to become more frequent in the coming decades as a result of climate change. Index insurance can theoretically help farmers to adapt and mitigate the risks posed by extreme weather events, providing a financial safety net in the event of crop damage or harvest failure. However, uptake of index insurance in practice has lagged far behind expectations. A key reason is that many existing index insurance p...
Evaluating maritime intelligent transportation systems: The case of using electric ferries and renewable energy in Türkiye Pense, Caner; Akınoğlu, Bülent Gültekin; Atik, Oğuz; Department of Earth System Science (2022-10-26) Climate Change and Global Warming are among the most critical global problems today. Their effects can be seen all over the world. The maritime sector contributes to global Climate Change and Global Warming with greenhouse gas emissions from coastal structures and ships. At the local level, it also negatively affects all life with environmental pollution, especially air and sea. Today, drive technologies are developing at a dizzying speed. In land transportation, electric vehicles are frequently seen. Elect...
Estimation of diffuse solar irradiation and its effects on PV power plant production at METU NCC Kavas, Genco; Taylan, Onur; Sustainable Environment and Energy Systems (2019-8) Excess amount of greenhouse gas (GHG) emission is the main reason of global warming. Renewable energy systems are one possible way to decrease GHG emission and solar energy is one of options; however, fluctuations on solar energy production is one of the main drawbacks. Accurate estimation of energy production from a solar power plant, such as PV-based plant is important to satisfy energy demand successfully. To be able to estimate energy production in advance, solar energy incident on PV modules should be ...
