What Causes the AMOC to Weaken in CMIP5?

Journal of Climate, 2020
AbstractIn a transient warming scenario, the North Atlantic is influenced by a complex pattern of surface buoyancy flux changes that ultimately weaken the Atlantic meridional overturning circulation (AMOC). Here we study the AMOC response in the CMIP5 experiment, using the near-geostrophic balance of the AMOC on interannual time scales to identify the ...

Representation of the Equatorial Undercurrent in CMIP5 Models

Journal of Physical Oceanography, 2020
AbstractThe Equatorial Undercurrent (EUC) is a vital component of tropical Pacific circulation, helping to modulate the state of the equatorial Pacific Ocean. Here we compare the representation of the EUC in models from phase 5 of the Coupled Model Intercomparison Project (CMIP5) with observations of the undercurrent.

The diurnal temperature range in the CMIP5 models

Climate Dynamics, 2014
This paper analyzes the diurnal temperature range (DTR) over land in simulations of the recent past and in future projections by 20 models participating in the Coupled Model Intercomparison Project phase 5 (CMIP5). The annually averaged DTR is evaluated for the present-day climate using two gridded datasets (HadGHCND and CRU).

QBO‐MJO Connection in CMIP5 Models

Journal of Geophysical Research: Atmospheres, 2020
AbstractRecent studies have shown that the quasi‐biennial oscillation (QBO) affects the boreal winter Madden‐Julian oscillation (MJO), its teleconnection, and even its subseasonal prediction skill. Despite its widespread influences, the QBO‐MJO connection has rarely been examined with a climate model. Here, we demonstrate that the QBO‐MJO connection is

Assessing the Reliability of Climate Models, CMIP5

2013
In spite of the yet incomplete subsample of the 5th phase of the Coupled Model Intercomparison Project (CMIP5) model ensemble to date, evaluation of these models is underway. Novel diagnostics and analysis methods are being utilized in order to explore the skill of particular processes, the degree to which models have improved since CMIP3, and ...

CMIP5 downscaling and its uncertainty in China

Global and Planetary Change, 2016
Abstract A comparison between the Coupled Model Intercomparison Project Phase 5 (CMIP5) data and observations at 735 meteorological stations indicated that mean annual temperature (MAT) was underestimated about 1.8 °C while mean annual precipitation (MAP) was overestimated about 263 mm in general across the whole of China.

CMIP5 Project and Some Results

2018
This chapter focused on Coupled Model Intercomparison Project, Phase 5 (CMIP5), and discussed various results. Starting from outlining very basic equations of global climate models (GCMs) as used in CMIP5 models, it described briefly about the aim and objective of the CMIP5 project.

Evaluation of the CFSv2 CMIP5 decadal predictions

Climate Dynamics, 2014
Retrospective decadal forecasts were undertaken using the Climate Forecast System version 2 (CFSv2) as part of Coupled Model Intercomparison Project 5. Decadal forecasts were performed separately by the National Center for Environmental Prediction (NCEP) and by the Center for Ocean-Land-Atmosphere Studies (COLA), with the centers using two different ...

El Niño teleconnections in CMIP5 models

Climate Dynamics, 2012
Teleconnections associated with warm El Nino/southern oscillation (ENSO) events in 20 climate model intercomparison project 5 (CMIP5) models have been compared with reanalysis observations. Focus has been placed on compact time and space indices, which can be assigned a specific statistical confidence. Nearly all of the models have surface temperature,

Brief Overview of FGOALS CMIP5 Experiments

2013
The overview provides a useful reference for FGOALS CMIP5 experiments. Major improvements of FGOALS component models used in CMIP5 are introduced. The foci are the improvements of physical packages used in AGCM and OGCM models. The CMIP5 experiments conducted by using two versions of FGOALS model are also summarized along with lists in tables.
