Abstract In this study, we identified the origin of moisture associated with tropical cyclones (TCs) precipitation in North Atlantic Ocean basin during their three well-differentiated life stages between 1980 and 2018. The HURDAT2 database was used to detect location 598 TCs genesis, maximum intensification peak, dissipation phases. global outputs Lagrangian FLEXPART model were then determine s...

The present study is focused on sediment core MD02–2521 in the Gulf of Tehuantepec (GT). This area, situated within Oxygen Minimum Zone (OMZ), rich marine resources due to seasonal upwelling caused by Tehuanos winds and a shallower thermocline representing an important economic sector region; however, has been focus little number studies. Benthic foraminifera (BF) are target proxy reconstruct b...

Climate patterns are natural processes that drive climate variability in the short, medium, and long term. Characterizing behind is essential to understand functioning of regional atmospheric system. Since investigations typically reveal only link extent influence specific regions, magnitude meteorological records usually remains unclear. The central Peruvian Andes affected by most common tropi...

Although accurate reconstructions of Amazonian palaeoclimates are central to understanding the distribution and history of Neotropical biodiversity, current reconstructions based on proxy data are discordant and subject to intense debate. We review some current thinking in Amazonian climatology and incorporate some new ideas in an attempt to explain the apparently contradictory records of palae...

[1] The secondary meridional circulation induced by convective momentum transport (CMT) within the ascending branch of the Hadley circulation is a missing dynamical mechanism that can cause common failure of general circulation models (GCMs) in simulating seasonal migration of the intertropical convergence zone (ITCZ) precipitation maximum across the equator. This failure is manifested by the m...

In this work we use a Lagrangian model (FLEXPART) to investigate the contribution of moisture from the Atlantic Warm Pool (AWP) to the atmospheric hydrological budget during the period from 1982 to 1999, and to identify which regions are affected by the moisture transport from this source. FLEXPART computes budgets of evaporation minus precipitation by calculating changes in the specific humidi...

The equatorial atmospheric variability shows a spectrum of significant peaks in the wavenumber– frequency domain. These peaks have been identified with the equatorially trapped wave modes of rotating shallow water wave theory. This paper addresses the observation that the various wave types (e.g., Kelvin, Rossby, etc.) and wavenumbers show differing signal strength relative to a red background....

Warmer SST and more rain in the Northern Hemisphere are observed year-round in the tropical eastern Pacific with southerly wind crossing the equator toward the atmospheric heating. The southerlies are minimal during boreal spring, when two precipitation maxima straddle the equator. Fourteen atmosphere– ocean coupled GCMs from the Coupled Model Intercomparison Project (CMIP3) and one coupled reg...

This study attempts to use a full spectrum of in-situ and remotely-sensed observations from meteorological satellite to examine the characteristics of the rainstorm that wreaked havoc on the stateofthe-art velodrome that stood out at the new National Stadium complex, Abuja, Nigeria, on Saturday, October, 2003, two hours to the closing ceremony of 8th All African Games and socio-economic implica...
