It is well known that the envelope of the Madden–Julian oscillation (MJO) consists of smaller-scale convective systems, including mesoscale convective systems (MCS), tropical cyclones, and synoptic-scale waves called ‘‘convectively coupled equatorial waves’’ (CCW). In fact, recent results suggest that the fundamental mechanisms of the MJO involve interactions between the synoptic-scale CCW and ...

In this study, a numerical examination of the significance of rotation and changeable gravitational field on the start of nanofluid convective movement in an anisotropic porous medium layer is shown. A model that accounts for the impact of Brownian diffusion and thermophoresis is used for nanofluid, while Darcy’s law is taken for the porous medium. The porous layer is subjected to uniform rotat...

We theoretically and experimentally evidence that fiber systems are convective systems since their nonlocal inherent properties, such as the dispersion and Raman effects, break the reflection symmetry. Theoretical analysis and numerical simulations carried out for a fiber ring cavity demonstrate that the third-order dispersion term leads to the appearance of convective and absolute instabilitie...

The intensification of tornado depends mainly on the synoptic conditions of the troposphere. The main objective of this paper is to differentiate the prevalent atmosphere from thermodynamically point of view. Atmospheric stability parameters such as Lifted Index (LI), Total Total Index (TT), Deep Convective Index (DCI), Wind Index (WI), Severe Weather Threat Index (SWEAT), Convective Available ...

[1] We show that simple thermodynamic models of convective plumes predict the area fraction of convective plumes (i.e., updrafts) in Titan’s atmosphere to be 12 smaller than on Earth. This result is in agreement with predictions by sophisticated dynamical models and with the relative tropospheric cloud cover, which is only 1% on Titan. Rainstorms on Titan, being so rare, may be violent. Citatio...

[1] The prodigious heat flux emitted from the surface of Jupiter’s moon Io is produced in the interior of the satellite by viscoelastic dissipation of tidal energy and is generally thought to be brought to the surface by convective motions. New models of Io’s equilibrium thermal state are constructed using self-consistent calculations of tidal heating and convective heat transport. These models...

Rain cells are structures which represent an important component of convective precipitation and a study of their properties represents a necessary step both towards improved stochastic models of small-scale precipitation and for the verification of deterministic high resolution local-area models. The case of intense convective precipitation in the tropics has been analysed in a recent study (v...

We have extended our published set of low mass AGB stellar models to lower metallicity. Different mass loss rates have been explored. Interpolation formulae for luminosity, effective temperature, core mass, mass of dredge up material and maximum temperature in the convective zone generated by thermal pulses are provided. Finally, we discuss the modifications of these quantities as obtained when...

1. INTRODUCTION † The primary cause of national airspace delay is convective weather. A large fraction of these delays is due specifically to en route weather (Allen et al., 2001). Crowded travel corridors such as the Great Lakes corridor from Chicago to New York experience the most significant en route convective weather delays. It is of particular importance within these high traffic regions ...
