Possible Causes for the Unprecedented Low/High Tropical Cyclone Activities in the Northern Pacific/Atlantic in 2023 El Niño

Geophysical Research Letters, Volume 51, Issue 22, 28 November 2024.
Abstract This study reported the unprecedented tropical cyclone (TC) activity in the western North Pacific (WNP) and North Atlantic (NA) during the developing year of the 2023/2024 El Niño. The possible causes behind these unusual features were addressed.

The Relative Importance of Ocean Advection and Surface Heat Fluxes During the Madden–Julian Oscillation in a Coupled Ocean–Atmosphere Model

Journal of Geophysical Research: Oceans, Volume 129, Issue 11, November 2024.
Abstract Intraseasonal variability of ocean surface mixed layer temperature (MLT) in the tropics can be linked to the Madden–Julian Oscillation (MJO), the main source of intraseasonal atmospheric variability in the tropics. Here, we conduct a boreal winter mixed layer heat budget using 10‐day forecast composites of a coupled ocean–atmosphere Numerical ...

Boreal summer intraseasonal oscillation-related precipitation in eastern China modulated by Pacific sea surface temperature

Environmental Research: Climate
The boreal summer intraseasonal oscillation (BSISO) is a key source of subseasonal to seasonal predictability, significantly enhancing precipitation in eastern China when BSISO convection is over the Indian Ocean. While background sea surface temperature

Intraseasonal Variability of Apparent Heat Source over the Arabian Sea and Its Relationship with East Asian Summer Precipitation

Journal of Marine Science and Engineering
Boreal summer intraseasonal oscillation (BSISO) is highly related to summer monsoon activities, tropical cyclones, flood disasters, and other extreme weather events in the Northern Hemisphere. The propagation of BSISO has considerable complexity.

What Controls the Interdecadal Enhancement in Interannual Variability of Summertime Intraseasonal Precipitation Over South China?

Journal of Geophysical Research: Atmospheres, Volume 129, Issue 17, 16 September 2024.
Abstract This study focuses on the interannual variability of summertime intraseasonal precipitation intensity (SIPI) over South China (SC) in the 30–90‐day range. The results demonstrate a significant increase in the interannual variability of SIPI over SC around the mid‐1990s.

Enhanced Pacific Northwest heat extremes and wildfire risks induced by the boreal summer intraseasonal oscillation

npj Climate and Atmospheric Science
The occurrence of extreme hot and dry summer conditions in the Pacific Northwest region of North America (PNW) has been known to be influenced by climate modes of variability such as the El Niño-Southern Oscillation and other variations in tropospheric ...

The interdecadal variations of cross-month correlation feature of the NWPSH

npj Climate and Atmospheric Science
The Northwest Pacific Subtropical High (NWPSH) presents a notable and even counterintuitive phenomenon: it shows a strong positive correlation between June and August (correlation coefficient: 0.55, significant at the 99.5% confidence level) during 1979 ...
