Future MJO Change and Its Impact on Extreme Precipitation and Temperature Over the Western US in CMIP6

open access: yesJournal of Geophysical Research: Atmospheres, Volume 130, Issue 5, 16 March 2025.
Abstract The Madden‐Julian oscillation (MJO) has remarkable impacts on global weather and climate systems. This study examines the future changes in MJO projected by 23 Coupled Model Intercomparison Project Phase 6 (CMIP6) models that produce a realistic MJO propagation in their historical runs. Results from the multi‐model mean show a ∼17% increase in

Quantifying CO2 and Non‐CO2 Contributions to Climate Change Under 1.5°C and 2°C Adaptive Emission Scenarios

open access: yesEarth's Future, Volume 13, Issue 3, March 2025.
Abstract The individual contributions of various human‐induced forcings under scenarios compatible with the Paris Agreement targets are highly uncertain. To quantify this uncertainty, we analyze three types of models with physical parameter perturbed large ensembles under global warming levels of 1.5 and 2.0°C. The scenarios use adaptive CO2 emissions,

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).

Coupled Ocean Atmosphere Processes and European Climate (COAPEC): improved understanding of the coupled climate system [PDF]

open access: yes, 2004
COAPEC (http://coapec.nerc.ac.uk/) is a five-year Directed Science Programme funded by the Natural Environment Research Council (NERC). COAPEC is providing advances in understanding the mechanisms by which the ocean and atmosphere interact, how these ...

Projecting community trophic structures for the last 120 000 years

open access: yesEcography, Volume 2025, Issue 3, March 2025.
Studying past community dynamics can provide valuable insights for anticipating future changes in the world's biota. However, the existing fossil record is too sparse to enable continuous temporal reconstructions of wholesale community dynamics. In this study, we utilise machine learning to reconstruct Late Quaternary community structure, leveraging ...

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.

Late Pliocene lakes and soils: a data-model comparison for the analysis of climate feedbacks in a warmer world [PDF]

open access: yes, 2013
Based on a synthesis of geological data we have reconstructed the global distribution of Late Pliocene soils and lakes which are then used as boundary conditions in a series of model experiments using the Hadley Centre General Circulation Model (HadCM3 ...

Environmental suitability throughout the late quaternary explains population genetic diversity

open access: yesEcography, Volume 2025, Issue 3, March 2025.
Genetic variation among populations is reflected in biogeographic patterns for many species, but general rules of spatial genetic variation have not been established. In this paper, we establish a theoretical framework based on projecting environmental Grinellian niches back through time to relate the present geographic distribution of population ...

Geostatistical assessment of HadCM3 simulations via NCEP reanalyses over Europe [PDF]

open access: yesAtmospheric Science Letters, 2004
AbstractThis article attempts to quantify the spatial uncertainties associated with extreme temperature's response, by assessing extremes derived from climate model data. This is undertaken by a comparison of the spatial pattern of a long‐term time‐series aggregation (1960/61–1989/90) for extreme temperatures simulated by a particular GCM (HadCM3) to ...

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
