Abstract As global temperatures continue to rise, the impact of heatwaves becomes increasingly striking. The increasing frequency and intensity of these events underscore the critical need to understand regional‐scale ...

Abstract The Madden‐Julian Oscillation (MJO) is a dominant intraseasonal oscillation in the tropics. As MJOs propagate over the Indian Ocean, some of them can be penetrated by fast‐moving equatorial Kelvin waves orig...

Abstract The Quasi‐Biennial Oscillation (QBO) of descending zonal winds is the leading mode of tropical stratospheric variability. Numerous studies have explored its connection with the troposphere, including its sensi...

Context. Fingering (thermohaline) convection has been invoked for several years as a possible extra-mixing which could occur in red giant stars; it is due to the modification of the chemical composition induced by nuclea...

An explicit time integrator without the CFL 

The effects of induced magnetic field, thermal and concentration convection on the peristaltic flow of Prandtl nanofluids are explored in this study in an inclined asymmetric channel. A detailed mathematical explanation ...

This paper presents the two-dimensional numerical study of mixed convection evaporation from an inclined corrugated wet plate subjected to a constant heat flux density. Assumptions were adopted and boundary conditions ar...

Foram estudados os fenômenos meteorológicos que ocorrem na Amazônia Central (Manaus) utilizando-se um conjunto de imagens de satélites, com o objetivo de identificar as oscilações que mais contribuem para a variabi...

Abstract Previous studies demonstrate that the Madden‐Julian Oscillation (MJO) modulates tropical cyclone (TC) activity over various locations worldwide. Since TCs are associated with anomalous large‐scale circulatio...

137Cs can be an important environmental contaminant due to fallout from nuclear reactor accidents and atomic weapons testing. Its contribution to the air gamma dose rate at 1 m height above contaminated ground depends on...

Abstract Typhoon Haikui (2023) brought an unprecedented rainstorm to Fuzhou, with a rainfall record of 360.4 mm in 12 hr and an instantaneous rain rate of 234 mm hr−1. This study investigates the evolution of preci...

This study is devoted to a dual-mode fractal radiator with a modified topology. Its key feature is the ability to alter end-wall orientation via gear engagement between wall-mounted gears and discrete positioning wheels....

A comprehensive structural, petrological, and geophysical study of the 385 ± 2 Ma Devonian El Hornito Pluton (EHP) in the Sierra Grande de San Luis, Argentina, is presented. We establish that the EHP results from the in...

Abstract Climate interventions like Marine Cloud Brightening have gained attention for their potential to protect vulnerable marine ecosystems from the worst impacts of climate change. Early modeling studies raised conce...

Abstract Climatological and monthly means are computed for radiosonde data at Manaus and Belém (1968-1976). Geopotencial height and wind data at upper levels show evidence of the meridional movement of a strongly diverg...

El trabajo muestra los resultados de los ensayos realizados en un secadero solar tendalero mixto con chimenea solar, en convección natural, y la simulación del funcionamiento de la chimenea solar. El sistema está cons...

Abstract This study examines the anthropogenic influences on the heavy precipitation event that occurred in early August 2022, South Korea, using a pseudo global warming (PGW) method with a convection‐permitting model....

Abstract The current study employs Bayesian-regularization optimizer technique with artificial neural networks (BROT-ANNs) to investigate the significance of local thermal non-equilibrium influences on wax + sand-bas...

The objective of the present study was to assess the effective thermal conductivity of the hair coat (k ef, mW.m-1.K-1) of Holstein cows in a tropical environment, as related to conduction and radiation in the absence of...

Abstract This study was carried out to develop jerky product utilizing spent hen meat. Manipulation of water activity (aw) of semi-dried meat with the addition of humectants (glycerol and sorbitol at the concentration of...

BackgroundThe thermal diffusivity and vertical seepage velocity of porous media are critical to characterizing the mechanisms underlying subsurface heat transfer. These two parameters are typically determined through inv...
