Transitions in convection driven by a horizontal temperature gradient

Physics Letters A, 1988
Abstract We report the first detailed experimental study of transitions in the convection of a low Prandtl number fluid driven by a horizontal temperature gradient. The observed states, from time independent to one frequency with noise, to pure noise, to two frequencies with noise, can be related to the two secondary flows predicted for a cavity with

Variations in horizontal density gradient forcing at the mouth of an estuary

1990
Puget Sound is a fjord-like estuary in which bottom-water intrusions are a dominant circulation feature that play a major role in the replacement of water below sill depth within the estuary. New observations on the inside and outside of the entrance sill show that while intrusions occur during neap tides as previously thought, the onset of the ...

Environmental gradients and the horizontal distribution of microcrustaceans in lakes

Freshwater Biology, 1998
1. The assemblage of suspension‐feeding microcrustaceans in lakes changes along a habitat gradient from nearshore to offshore. This gradient of microcrustaceans was explored in relation to differences in macrophytes and the associated changes in water chemistry, food resources and types of predators.2.

Magnetic surveying using horizontal gradient vectors

Geophysics, 1977
Abstract It was pointed out some time ago (Bhattacharyya, 1965) that the total intensity anomaly of a magnetic field ΔT in the direction of the normal magnetic field of earth is expressed by the equation, ΔT=−δ(ΔV)/δt. Here ΔV denotes the anomaly of the magnetic potential and t the unit vector in the direction of earth's undisturbed ...

Vertical variation modeling of the tropospheric horizontal gradient

Accurate modeling of the horizontal and vertical variation of the tropospheric horizontal gradient is crucial for correcting space-geodetic tropospheric delays and retrieving atmospheric water vapor. To date, the horizontal variation in the gradient has been well represented by the operational grid-wise products, such as grid-wise GRAD.

Double-diffusive interleaving due to horizontal gradients

Journal of Fluid Mechanics, 1983
In this paper we present a linear stability analysis for an unbounded, vertically stratified fluid which has compensating horizontal temperature and salinity gradients, so there is no horizontal density gradient. We obtain the most unstable perturbation for given linear horizontal and vertical gradients and calculate the growth rates, the vertical ...
