Keywords: Currents; Mesoscale processes; Sea surface temperature; Satellite observations1. IntroductionTropical instability waves (TIWs) are a dominant mesoscale (1000-km scale) variability of sea surface height (SSH) and velocities (Fig. 1a), propagating westward from the eastern to the central equatorial Pacific Ocean. Numerous studies have described TIWs (e.g., Düing et al. 1975; Legeckis 1977; Miller et al. 1985; Qiao and Weisberg 1995; Willett et al. 2006; Wang et al. 2019).

AbstractDeep convection in the Indo-Pacific warm pool is vital in driving global atmospheric overturning circulations. Year-to-year variations in the strength and location of warm pool precipitation can lead to significant local and downstream hydroclimatic impacts, including floods and droughts. While the El Niño-Southern Oscillation (ENSO) is recognized as a key factor in modulating interannual precipitation variations in this region, atmospheric internal variability is often as important.

AbstractThe North Pacific Oscillation (NPO), an important mode of atmospheric variability, is a crucial trigger for the development of El Niño-Southern Oscillation (ENSO) via the seasonal footprinting mechanism. How the NPO effect on ENSO changes in response to greenhouse warming remains unclear, however.

AbstractThe responses of the Earth’s climate system to positive and negative CO2 emissions are not identical in magnitude, resulting in hysteresis. In particular, the degree of global precipitation hysteresis varies markedly among Earth system models. Based on analysis of Earth’s energy budget, here we show that climate sensitivity controls the degree of global precipitation hysteresis.
