Sub-Suns and Low Reynolds Number Flow
The phenomenon called the ``sub-Sun'' is the specular reflection of sunlight by horizontally oriented plates of ice. Although well-known in meteorological optics, the hydrodynamics of the…

Interdecadal variability and oceanic thermohaline adjustment
Changes in the strength of the thermohaline overturning circulation are associated, by geostrophy, with changes in the east-west pressure difference across an ocean basin. The tropical-polar density…

Entropic "sound" in the atmosphere
It is shown that small, local disturbances of entropy in the atmosphere may give rise to "sound" waves propagating with a velocity which depends on the amplitude ratio of the local relative…

Analysis and modeling of scale-invariance in plankton abundance
The power spectrum, S, of horizontal transects of plankton abundance are often observed to have a power-law dependence on wavenumber, k, with exponent close to -2: S(k) k-2 over a…

Kardar-Parisi-Zhang model for the fractal structure of cumulus cloud fields
We model the ascent of warm, moist air in the Earth's atmosphere by turbulent convection and expansion with the KPZ equation, familiar in the physics literature on surface growth. Clouds form in…

A Stochastic Diffusion Model of Climate Change
We present a model for variations in atmospheric temperature from time scales of one day to one million years based on a stochastic diffusion (random walk) model of the turbulent transport of heat…

Hadley circulations and large scale motions of moist convection in the two dimensional numerical model
As a tool for understanding the meridional circulation of the atmosphere, a two-dimensional ( latitude -- height ) numerical model is used to clarify the relationship between the Hadley circulation…

Mechanisms of Seasonal - ENSO interaction
The mechanisms of interaction between the seasonal cycle and ENSO are investigated using the Zebiak and Cane ENSO prediction model. The most dominant seasonal effect is found to be due to the wind…

Interpretation of TOVS Water Vapor Radiances Using a Random Strong Line Model
This study illustrates the application of a random strong line (RSL) model of radiative transfer to the interpretation of satellite observations of the upwelling radiation in the 6.3 micron water…

The stability of a zonally averaged thermohaline circulation model
A combination of analytical and numerical techniques are used to efficiently determine the qualitative and quantitative behaviour of a one-basin zonally averaged thermohaline circulation ocean model.…

A Scaling Theory for Horizontally Homogeneous, Baroclinically Unstable Flow on a Beta-Plane
The scaling argument developed by Larichev and Held (1995) for eddy amplitudes and fluxes in a horizontally homogeneous, two-layer model on an f-plane is extended to a beta-plane. In terms of the…

A linear thermohaline oscillator driven by stochastic atmospheric forcing
The interdecadal variability of a stochastically forced four-box model of the oceanic meridional thermohaline circulation (THC) is described and compared to the THC variability in the coupled…

North Atlantic thermohaline circulation predictability in a coupled ocean-atmosphere model
Predictability of the North Atlantic thermohaline circulation (THC) variability as simulated in the GFDL coupled ocean-atmosphere general circulation model is established for a set of ensemble…
