The Ganges, Brahmaputra and Meghna (GBM) river basins occupy about 1.75 x 10 km of the Himalayan region. More than half a billion people in Nepal, India, Bhutan and Bangladesh are directly or indirectly dependent on the water resources of the GBM rivers. These river basins are characterized by diversified climatic patterns. Analyses of trends and persistence in precipitation over these river ba...

Buharlaşma miktarındaki değişimin doğru bilinmesi, su kaynaklarının yönetimi, ile ilgili yapıların tasarlanması ve eylem planlarının hazırlanması için önemlidir. Bu çalışmada, Türkiye’nin önemli tarımsal alanlarını barındıran Güneydoğu Anadolu Bölgesi’ndeki Gaziantep, Şanlıurfa Mardin istasyonlarına ait aylık toplam tava buharlaşması verilerinin trendleri, parametrik olmayan Mann-Kendall (MK) t...

Detection of abrupt change is a key issue for understanding the facts and trends of climate change, but it is also a difficult task in practice. The Mann-Kendall (MK) test is commonly used for treating the issue, while the results are usually affected by the correlation and seasonal characters and sample size of series. This paper proposes a discrete wavelet entropy-aided approach for abrupt ch...

The methods reviewed here are primarily those that are used in atmospheric and oce-anic (physical and biological) studies. These methods are divided into four groups, depending on the type of shifts they are designed to detect, and placed in Tables 1-4. The tables are self-explanatory and provide a brief description of each method, along with the basic references , as well as their strong and w...

Climate change information at the scale of basin is vital for planning, development and use water. The Tapi climatically responsive. Hydrological response a based mainly on rainfall temperature. Variations in climate regional scales impacts fundamental features our life. Thus, present work, trend analyses time series (1971-2004) minimum, mean, maximum temperatures rainfallis performed monthly, ...

This study proposed a multi-target hierarchical detection (MTHD) method to simultaneously and automatically detect multiple directional land cover changes. MTHD used a hierarchical strategy to detect both abrupt and trend land cover changes successively. First, Grubbs’ test eliminated short-lived changes by considering them outliers. Then, the Brown-Forsythe test and the combination of Tomé’s m...

Abstract Regarding climatic diversity in Iran and the dependence of many outdoor activities (occupational, recreational, tourism attraction, etc.) on conditions, this study conducted aiming to evaluate thermal comfort fluctuations Iran. Thermal different climates were investigated between 1985 2014 using recorded meteorological data 40 synoptic stations. The Mann-Kendall test Sen’s Slope used a...
