Predictability of SST in an Idealized, One-Dimensional, Coupled Atmosphere–Ocean Climate Model with Stochastic Forcing and Advection
Publisher: American Meteorological Society
Abstract: The predictability of sea surface temperature (SST) is examined through analysis of an idealized, one-dimensional, stochastically forced climate model. The influence on SST predictability of including advection by a constant ...
Surface Signatures of a Dry Nocturnal Gust Front
Publisher: American Meteorological Society
Abstract: Sudden changes in surface meteorological parameters were observed to propagate across a densely-instrumented network in central Illinois during a summer night in 1979. The changes were due to the outflow from an eastward ...
Predictability of SST in a Stochastic Climate Model and Its Application to the Kuroshio Extension Region
Publisher: American Meteorological Society
Abstract: The influence of deterministic forcing on SST predictability is investigated in a zero-dimensional, stochastic, coupled atmosphere?ocean climate model. The SST anomaly predictability time is found to be very sensitive to ...
Direct Evidence of an Oceanic Inverse Kinetic Energy Cascade from Satellite Altimetry
Publisher: American Meteorological Society
Abstract: Sea surface height measurements from satellites reveal the turbulent properties of the South Pacific Ocean surface geostrophic circulation, both supporting and challenging different aspects of geostrophic turbulence theory. ...
Length Scales of Eddy Generation and Nonlinear Evolution of the Seasonally Modulated South Pacific Subtropical Countercurrent
Publisher: American Meteorological Society
Abstract: The dynamical processes behind the seasonal modulation of the two-dimensional eddy kinetic energy (EKE) wavenumber spectrum in the Subtropical Countercurrent region of the South Pacific are investigated with 14 yr of ...
Spectral Energy Fluxes in Geostrophic Turbulence: Implications for Ocean Energetics
Publisher: American Meteorological Society
Abstract: The energy pathways in geostrophic turbulence are explored using a two-layer, flat-bottom, f-plane, quasigeostrophic model forced by an imposed, horizontally homogenous, baroclinically unstable mean flow and damped by ...
Central Illinois Cold Air Funnel Outbreak
Publisher: American Meteorological Society
Abstract: Numerous cold air funnels developed in close proximity over central Illinois on 23 May 1988 as the core of an upper-level cutoff low pressure center passed over the region. Five separate funnels were observed by one of the ...
On Quadratic Bottom Drag, Geostrophic Turbulence, and Oceanic Mesoscale Eddies
Publisher: American Meteorological Society
Abstract: Many investigators have idealized the oceanic mesoscale eddy field with numerical simulations of geostrophic turbulence forced by a horizontally homogeneous, baroclinically unstable mean flow. To date such studies have ...
A Simple Objective Method Used to Forecast Convective Activity during the 1989 PACE Cloud-seeding Experiment
Publisher: American Meteorological Society
Abstract: A simple objective procedure used exploratively to forecast the occurrence, height, and coalescence activity of summertime convective clouds in Illinois during the cloud-seeding trials of the 1989 Precipitation Augmentation ...
