A study of the sensitivity of ENSO to the mean climate [PDF]

open access: yesAdvances in Geosciences, 2006
We study the dependence of the simulated ENSO on the mean simulated climate in the HadCM3 GCM and attempt to understand its relation with results from intermediate-complexity models (ICMs).

Effect of ENSO phase on large-scale snow water equivalent distribution in a GCM [PDF]

open access: yes, 2009
Understanding links between the El Nino-Southern Oscillation (ENSO) and snow would be useful for seasonal forecasting, but also for understanding natural variability and interpreting climate change predictions.

Evaluating migration hypotheses for the extinct Glyptotherium using ecological niche modeling

open access: yesEcography, Volume 2025, Issue 5, May 2025.
The formation of the Isthmus of Panama allowed for migrations between the once separated continents of North and South America. This led to one of the greatest documented interchanges of biota in Earth history, wherein an array of species across many groups migrated between the continents.

An assessment of future climatic and anthropogenic impacts on the hydrological system of a semi‐arid catchment

open access: yesIrrigation and Drainage, Volume 74, Issue 2, Page 834-860, April 2025.
Abstract Climate and catchment characteristics, particularly land and water use and management, may vary according to the population growth rate, future food habits and water demands. Three climate simulations corresponding to the Intergovernmental Panel on Climate Change, Special Report on Emissions Scenarios (A1B) were downscaled using the ‘Providing

رویکردی جدید برای ارزیابی عملکرد مدل‌های AOGCM در شبیه‌سازی رواناب [PDF]

open access: yesپژوهش‌های حفاظت آب و خاک, 2015
سابقه و هدف: پدیده تغییر اقلیم بر بخش‌های مختلف تأثیر می‌گذارد که منابع آب از مهم‌ترین آنها است. لین و همکاران (1999) بررسی کردند که کشورهای واقع در عرض جغرافیایی پایین، بیشترین تبعات منفی این پدیده را متحمل خواهند شد (9). پیش‌نیاز ارزیابی اثرات منطقه‌ای

Sea surface temperature inter-hemispheric dipole and its relation to tropical precipitation

open access: yesEnvironmental Research Letters, 2013
Using different SST datasets, the variability of zonal mean SSTs is investigated. Besides the global warming mode, the variability is dominated by one equatorially symmetric mode and one antisymmetric mode.

Performance Evaluation of Statistical Downscaling Model (SDSM) in Forecasting Precipitation in two Arid and Hyper arid Regions

open access: yesمجله آب و خاک, 2014
One of the most important problems in the management and planning of water resources is to forecast long-term precipitation in arid region and hyper arid regions.

The effect of doubled CO2 and model basic state biases on the monsoon-ENSO system. II: Changing ENSO regimes [PDF]

open access: yes, 2007
Integrations of a fully-coupled climate model with and without flux adjustments in the equatorial oceans are performed under 2×CO2 conditions to explore in more detail the impact of increased greenhouse gas forcing on the monsoon-ENSO system.

Impact of Model Tuning on Simulated Mid‐Pliocene Warming

open access: yesPaleoceanography and Paleoclimatology, Volume 40, Issue 4, April 2025.
Abstract A tuned version of HadCM3 (HadCM3t) is used to simulate the climate of the mid‐Pliocene warm period (mPWP) and is compared with the original untuned version of HadCM3 (HadCM3u). After the tuning, HadCM3t performs as well as HadCM3u in simulating the preindustrial climate, but aligns better with the reconstructed mPWP sea surface temperature ...

Impact of climate change on freshwater ecosystems: a global-scale analysis of ecologically relevant river flow alterations [PDF]

open access: yes, 2010
River flow regimes, including long-term average flows, seasonality, low flows, high flows and other types of flow variability, play an important role for freshwater ecosystems.
