Modulation of tropical stratospheric gravity wave activity and the ITCZ position by modes of climate variability using radio occultation and reanalysis data [PDF]
Atmospheric Chemistry and PhysicsThe Intertropical Convergence Zone (ITCZ) is a dominant feature of tropical climate characterized by intense convection that influences global atmospheric circulation and serves as a primary source of stratospheric gravity waves (GWs), which transport ...

Contrasting Impacts of Three Extreme El Niños on Double ITCZs over the Eastern Pacific Ocean
Atmosphere, 2021 In the recent four decades, there were three record-breaking El Niño events: 1982/1983, 1997/1998, and 2015/2016 events. A double intertropical convergence zone (ITCZ) pattern distinctively emerges over the eastern Pacific Ocean during boreal spring ...

The Atlantic ITCZ bias in CMIP5 models [PDF]
Climate Dynamics, 2014 Precipitation over the tropical Atlantic in 24 atmospheric models is analyzed using an object-based approach, which clusters rainy areas in the models as precipitation objects and calculates their properties such as size, amplitude, and location. Based on the distribution of precipitation objects over land and over ocean, two classes of models emerge ...

ENSO or the Atlantic: Which Actually Governs the Hydrological Vulnerability of the Caatinga?
International Journal of Climatology, EarlyView.This study challenges the traditional ENSO‐centric paradigm of rainfall variability in the Caatinga by demonstrating that the Tropical Atlantic exerts a statistically dominant influence on regional hydrological vulnerability. Using a seasonal ARX/HAC model and CHIRPS data, we establish a new hierarchy of climatic drivers across six rainfall districts ...

Climate Change Projections for Mexico in the 21st Century
International Journal of Climatology, EarlyView.Projected national temperature by the end of the century under four SSP scenarios. Under the low‐emission pathway (SSP1‐2.6), warming increases more gradually, whereas under the high‐emission scenario (SSP5‐8.5), temperatures exceed 5°C by 2100. These results strengthen the scientific basis for climate adaptation planning and long‐term decision‐making ...

International Journal of Climatology, EarlyView.Australia has different levels of exposure to tropical cyclones. Using historical records, this study investigates the spatial variability of tropical cyclone formation across the Southeast Indian–South Pacific basin, quantifies the exposure of different parts of Australia to tropical cyclone weather events, and examines decadal variability in cyclone ...

Journal of the Atmospheric Sciences, 2001 Abstract Chao's numerical and theoretical work on multiple quasi equilibria of the intertropical convergence zone (ITCZ) and the origin of monsoon onset is extended to solve two additional puzzles. One is the highly nonlinear dependence on latitude of the “force” acting on the ITCZ due to the earth's rotation, which makes the multiple quasi equilibria ...

Response of the ITCZ to Northern Hemisphere cooling [PDF]
Geophysical Research Letters, 2006 Climate simulations, using models with different levels of complexity, indicate that the north‐south position of the intertropical convergence zone (ITCZ) responds to changes in interhemispheric temperature contrast. Paleoclimate data on a variety of timescales suggest a similar behavior, with southward displacements of the ITCZ and associated changes ...

Inter ocean basin moisture fluxes and the onset of the summer rainy season over southern Mexico
Frontiers in Climate, 2022 The onset of the rainy season in monsoonal climates is a key element for the development of water related activities. In southern Mexico, it starts in late May or early June, while in western and northwestern part of the country in begins between early ...

Quarterly Journal of the Royal Meteorological Society, EarlyView.This study evaluates the subseasonal predictive skill of tropical–extratropical cloud bands across four subtropical convergence zones in ECMWF reforecasts (2003–2022). Results show that, while exact daily predictions are limited to one week, accounting for temporal displacement improves forecast skill significantly, revealing a systematic early onset ...
