Subseasonal predictability and Rossby wave dynamics of blocking high during transitional seasons: insights from three successive events in May–June 2023

Zhixiang Li, Jianhua Lü, Yimin Liu

Extended-range prediction during the transitional seasons remains particularly challenging due to the volatile large-scale circulation background. This study investigates the dynamical linkages, Rossby wave characteristics, and subseasonal predictability of three successive atmospheric blocking episodes over Canada, the Ural Mountains, and Europe in …

Systematic Benchmarking of Climate Models: Methodologies, Applications, and New Directions

Birgit Haßler, Forrest M. Hoffman, Rebecca L. Beadling, Ed Blockley et autres

Abstract As climate models become increasingly complex, there is a growing need to comprehensively and systematically assess model performance with respect to observations. Given the increasing number and diversity of climate model simulations in use, the community has moved beyond simple model …

The Vertical Structure of Radiative Forcing and its Effect on Rapid Tropospheric Adjustment

Tao Wang, Jianhua Lü

Abstract The increase in CO 2 not only changes the energy balance at the top of the atmosphere but also alters the heating rate at every height level of the troposphere. This uneven vertical heating has significant implications for rapid adjustments within …

Birgit Haßler, Forrest M. Hoffman, Rebecca L. Beadling, Ed Blockley et autres

As climate models become increasingly complex, there is a growing need to comprehensively and systematically assess model performance with respect to observations. With increasing spatial and temporal resolutions, and a lengthening record of observational data, the community has moved beyond simple model …

Rotational Flow Dominates Abrupt Seasonal Change in Zonally Asymmetric Tropical Meridional Circulation

W. Yao, Jianhua Lü, Yimin Liu

By defining a pseudo meridional overturning streamfunction (Ψpseudo) at any zonal sector and defining a new vector-type, dual-component index (Abrupt Seasonal Change Index, ASCI), we diagnose zonally asymmetric abrupt seasonal change (ASC) of tropical meridional circulation. Ψpseudo converges to traditional, meridional overturning …

Rotational Flow Dominates Abrupt Seasonal Change in Zonally Asymmetric Tropical Meridional Circulation

W. Yao, Jianhua Lü, Yimin Liu

The seasonality of the tropical meridional circulation evolves differently across different regions, governs the onset and retreat of monsoons and migration of tropical precipitation, thereby influencing agricultural productivity and disaster preparedness in the tropics and subtropics. By defining a pseudo meridional overturning …

Paradigm shifts of climate science for climate solutions

Jianhua Lü

Climate science is an indispensable part of climate solutions, and an era of climate actions necessitates certain paradigm shifts of climate science to better support viable climate actions and solutions. Three paradigm shifts are exemplified, namely (1) transcending the boundaries between physical …
