1. Mixed convection heat transfer in rotating vertical elliptic ducts
This paper presents an investigation into the solution of laminar mixed convective heat transfer in vertical elliptic ducts containing an upward flowing fluid rotating about a parallel axis. The coupled system of normalized conservation equations are solved using a power series expansion in ascending powers of rotational Rayleigh Number, Ratau - a measure of

2. Inclusion of the momentum perturbation in the kain-fritsch cumulus parameterization scheme and impacts on a convective rain case / Inclusão da perturbação de momentum no esquema de parametrização de cumulus kain-fritsch e impactos sobre um caso de chuva convectiva
The objective of this work is to insert the vertical transport of momentum through the mass flux in the Kain-Fritsch convective parameterization scheme. The momentum fluxes were inserted in the KF scheme in a similar way to the existing heat fluxes. Experiments were accomplished in the two domains, one experiment with cloud updraft (FM1) and one experiment i

3. Transient convective heat transfer
In nature, as well as within the human-made thermal systems, the time-variable regimes are more commonly encountered, if not always, than the permanent regimes. Nevertheless, studies in convection are still more frequent in the permanent regimes, undoubtedly due to the related difficulties in calculation in terms of time and cost of computation. One may dist

4. Interação das perturbações convectivas iniciadas na costa norte do Brasil com os distúrbios ondulatórios de leste / Interaction of the convective perturbations initiated in the northern coast of Brazil with the easterly waves
Investigaram-se os aspectos climatológicos das perturbações convectivas (PC) iniciadas na Costa Norte do Brasil (CNB) e sua relação com os Distúrbios Ondulatórios de Leste (DOL). Utilizou-se dados de fração de nuvens convectivas do ISCCP, de 1984 a 1998, com resoluções horizontal de 2,5o e temporal de 3 h, e um procedimento objetivo de tracking pa

5. Efeitos Inter-Hemisfericos de intensas fontes tropicais de calor / Inter-Hemispheric effects of strong tropical heat sources
The response over South America of the latent heat release in a strong perturbation (hurricane) moving over North Tropical Atlantic Ocean is investigated using a nonlinear semi-Lagrangian two layer primitive equation model. The model results show that such a perturbation propitiates a coupling with frontal system in the Southern Hemisphere and the convective
