The Double-ITCZ Bias in CMIP6 Models

2020
<p>The double-Intertropical Convergence Zone (ITCZ) bias is one of the most outstanding problems in climate models. This study seeks to examine the double-ITCZ bias in the latest state-of-the-art fully coupled global climate models that participated in Coupled Model Intercomparison Project (CMIP) Phase 6 (CMIP6) in comparison to ...

ITCZ dynamics as seen by complex network theory

2020
<p>The intertropical convergence zone (ITCZ) is an important component of the tropical rain belt. Climate models still struggle to represent the ITCZ and differ substantially in its simulated response to climate change. Here, we study to what extent complex network theory, which can effectively extract spatio-temporal variability

We need to simulate more northern ITCZs and less southern ITCZs over the east Pacific Ocean in coupled climate models

Journal of Geophysical Research: Atmospheres
Tropical precipitation biases have persisted since the very first generations of climate models. These biases are highly sensitive to the region and/or season of interest, with commonalities in the east Pacific and Atlantic Ocean basins, possibly due to their similar observed climatological northern hemisphere intertropical convergence zone (ITCZ ...

We need to simulate more double ITCZs and less southern ITCZs in reanalyses and coupled climate models

Model biases in tropical precipitation have persisted for nearly 30 years. These biases are highly sensitive to the region and/or season of interest, with commonalities in the east Pacific and Atlantic Ocean basins, possibly due to their similar observed climatological northern hemisphere intertropical convergence zone (ITCZ).

Evaluation of precipitation and ITCZ characteristics in CMIP6 models

The Intertropical Convergence Zone (ITCZ) is a band of low pressure near the equator, where the trade winds converge. It is usually accompanied by cloudiness and heavy precipitation, and it migrates northward and southward, following the sun in different seasons.

The Climatology of the Itcz Based on Outgoing Longwave Radiation

1987
The outgoing longwave radiation data derived from the NOAA polar orbiting satellites during the period from June 1974 to May 1984 have been used to construct the climatic charts of the ITCZ on the whole globe. The monthly variation of the ITCZ over different parts of the tropical continents and oceans is inspected separately.
