Air-sea interaction at contrasting sites in the eastern tropical Pacific : mesoscale variability and atmospheric convection at 10°N
The role of ocean dynamics in driving air-sea interaction is examined at two contrasting sites on 125°W in the eastern tropical Pacific Ocean using data from the Pan American Climate Study (PACS) field program. Analysis based on the PACS data set and satellite observations of sea surface …

The structure of the upper ocean, atmosphere and heat fluxes - Tropical Indian Ocean
… very little is currently known about the marine-atmospheric processes in the Indian Ocean tropics. To address this lack of information, the structure of the upper ocean and lower atmosphere as well as the surface heat fluxes in the tropical Indian Ocean have been investigated. This was done by a …

Thinning and turbulence in aqueous films
… decade. Thin liquid films serve as paradigms of atmospheric convection, thermal convection in the Earth’s mantle or turbulence in magnetohydrodynamics. Recent research on colloids, interfaces and nanofluids lead to advances in the developtment of micro-mixers (lab-on-a-chip devices). In this …

Laminar Analogues of Atmospheric Phenomena
… the process of eye formation in shallow rotating convection. Through a series of numerical simulations we observe that, as thermal forcing is increased, the system undergoes a Hopf bifurcation from a steady state to one in which the eye oscillates. Examining the nature of the oscillations we …

Dependence of continental severe convective instability on climatological environmental conditions
Most of Earth's strongest atmospheric convection occurs over the continents, where potential energy is stored over time in metastable vertical profiles, only to be released rapidly by severe storms. In contrast to equilibrium-state convection in tropical ocean regions, there is a relative paucity …

Arctic daily temperature and precipitation extremes: Observed and simulated physical behavior
… M. Glisan</p> <p>Department of Geological and Atmospheric Sciences, Iowa State University, Ames, Iowa</p> <p>ABSTRACT</p> <p>Simulations using a six-member ensemble of Pan-Arctic WRF (PAW) were produced on two Arctic domains with 50-km resolution to analyze precipitation and temperature …

Convective Dynamics of the Tropical Atmosphere in Three Idealized Approaches
Atmospheric convection organized at large spatial scales significantly influences precipitation patterns and weather events in tropical and subtropical regions, and has a rich, two-way interaction with Earth's climate. Tropical cyclones, mesoscale convective complexes, heat lows, and the rainbands …

Wildfires in the Cape floristic region : exploring vegetation and weather as drivers of fire frequency
… Easterly wave lows are associated with strong atmospheric convection whereas tropical temperate troughs are associated with pre-frontal conditions and strong, hot and dry winds. The frequencies of these synoptic states were shown to have increased in recent decade. The factors influencing fire …

Causal history analysis of complex system dynamics
… of stream chemistry, the chaotic behavior of atmospheric convection, the entropy production due to the dissipative structure of plants, and so forth. Multivariate interactions of the entire system definitely play a key role in sustaining these emergent behaviors, which will not happen solely …

Simulating organization of convective cloud fields and interactions with the surface
… to the transition between shallow and deep convection. The thermodynamic state of the boundary layer is forced by the amount of surface fluxes from below. Conversely, landscape patterns and land-cover heterogeneity may equally give rise to focused regions for deep convection triggering, in …
