The Effect of Climate Change on Volume of Water Resources and Transfer of Inter-Basin Water [PDF]

open access: yesعلوم و مهندسی آبیاری, 2019
Climate change is a serious challenge to human interest by its adverse effect on various sectors, such as water sources, agriculture, and energy. According to IPCC report, the average annual temperature of the earth has been raised between 0.3 to 0.6º ...

Twin experiments with the equivalent weights particle filter and HadCM3 [PDF]

open access: hybridQuarterly Journal of the Royal Meteorological Society, 2015
This article investigates the use of a particle filter for data assimilation with a full‐scale coupled ocean–atmosphere general circulation model. Synthetic twin experiments are performed to assess the performance of the equivalent weights filter in such a high‐dimensional system.

Investigating the Uncertainty Effect of GCMs Output on the Prediction of Meteorological Parameters in Golestan Province [PDF]

open access: yesعلوم و مهندسی آبیاری, 2019
One of the important issues in assessing climate change using the output of General Circulation Models (GCMs) is their uncertainty so that the outputs of a model in a region may vary with another model in the same region.

Evaluation of statistical downscaling model's performance in projecting future climate change scenarios

open access: yesJournal of Water and Climate Change, 2023
Statistical downscaling (SD) is preferable to dynamic downscaling to derive local-scale climate change information from large-scale datasets. Many statistical downscaling models are available these days, but comparison of their performance is still ...

ارزیابی اثرات تغییر‌اقلیم و تغییرکاربری‌اراضی بر پاسخ هیدرولوژیک حوزه‌ آبخیز اسکندری [PDF]

open access: yesجغرافیا و مخاطرات محیطی, 2017
علاوه بر تغییر‌اقلیم، تغییر‌کاربری‌اراضی به عنوان یک عامل جانبی اثرات مهمی بر سیلاب دارد. لذا پیش-بینی اثر این دو پارامتر بر وضعیت سیلاب دهه‌های آتی، راهگشای مقابله با این پدیده خواهد بود.

Climate change assessment under greenhouse gases emission scenarios: Urmia Lake Basin [PDF]

open access: yesمدیریت بیابان, 2017
In the past few decades, an increase in greenhouse gases has caused global climate imbalance on the Earth which is referred to as "climate change". Studies have shown that this phenomenon has direct and indirect impacts on the natural, economic and ...

Investigating the Impact of CO2 on Low-Frequency Variability of the AMOC in HadCM3 [PDF]

open access: hybridJournal of Climate, 2017
Abstract This study investigates the impact of CO2 on the amplitude, frequency, and mechanisms of Atlantic meridional overturning circulation (AMOC) variability in millennial simulations of the HadCM3 coupled climate model. Multichannel singular spectrum analysis (MSSA) and empirical orthogonal functions (EOFs) are applied to the AMOC at
