Abstract In recent years, greenhouse gas emissions have caused extensive changes in the global climate. Climate change leads to extreme events, such as droughts. The present study investigates precipitation and temperature variations past future drought characteristics Iran through data from 40 synoptic stations 33 general circulation models (GCMs) under RCP4.5 RCP8.5 scenarios. As a first step...

The present study was focused to examine the combined effects of climate and ultraviolet-B radiation on conifer tree-ring density. Statistical methods were employed to extract tree responses in annual ring density and to identify functional relationship in trees when the level of ultraviolet-B radiation changes regardless of climate variations. In this study, the consideration was given to the ...

Abstract Global warming is threatening human population, one of which the frequent climate disasters, i.e., floods and drought, affect global food security. However, assessment regional climatic changes constrained by lack high-quality long-term data. Taking Northern Region Peninsular Malaysia as study area, this paper aims to assess performance NASA POWER in estimating annual seasonal variabil...

A rain gauge network should serve general as well as specific purposes such as water supply, hydropowergeneration, flood forecasting, irrigation, and flood control. The level of accuracy a network can achieve depends onthe number and locations of gauges in the network. In this study, a rain gauge network was designed for Hormozganprovince in the south of Iran. Monthly rainfall totals from 124 r...

Drought is a major problem in the world and has become more severe recent decades, especially arid semi-arid regions. In this study, Google Earth Engine (GEE) app been implemented to monitor spatiotemporal drought conditions over different climatic The allows every user perform analysis region for period of their choice, benefiting from huge GEE dataset free open data as well its fast cloud-bas...

Bioclimate alteration unquestionably poses a current but also potential future threat to natural and agricultural ecosystems their services. In this scope, the present bioclimatic footprint of Central European territory is investigated presented. For first time, an ultrahigh spatial resolution (<250 m) de Martonne index analyzed over entire area, as well for individual countries (Austria, Sw...

The changing climate is closely related to changes in the bioclimate. This research deals with present bioclimate and its projected evolution over entirety of natural agricultural lands south-eastern Europe individual countries (Bulgaria, Greece, Kosovo, N. Macedonia, Romania, Serbia). For this purpose, an ultrahigh spatial resolution de Martonne bioclimatic index pattern was elaborated analyse...

Aridity conditions in semi-arid lands with warm climates are key variables that must be assessed to properly manage water and plan minimise the threat of desertification. This study analyses spatial distribution aridity Extremadura, southwestern Spain, using De Martonne index (IDM), considering a historical reference period (1971–2005) three-time intervals: 2006–2035 (near future), 2036–2065 (m...
