Inter‐Model Spread of North Tropical Atlantic Trans‐Basin Effect Substantially Biases Tropical Pacific Sea Surface Temperature Multiyear Prediction

A model of the tropical Pacific sea surface temperature climatology

A model for the climatological mean sea surface temperature (SST) of the tropical Pacific Ocean is developed. The upper ocean response is computed using a time dependent, linear, reduced gravity model, with the addition of a constant depth frictional surface layer. The full three-dimensional temperature equation and a surface heat flux parameterization that requires pecification ofonly wind spe...

Multiyear Observations of the Tropical Atlantic Atmosphere

T he tropical Atlantic Ocean is a region of significant meteorological and oceanographic interest in terms of atmospheric chemistry and mesoscale-to-synoptic dynamical and thermodynamical processes. Nonmaritime air masses from the African continent advect out over the Atlantic within easterly winds and waves, significantly impacting the meteorology and climate dynamics downstream into the Weste...

Tropical Pacific Sea-Surface Temperatures and Preceding Sea Level Pressure Anomalies in the Subtropical North Pacific

Tropical Atlantic Biases in CCSM4

This paper focuses on diagnosing biases in the seasonal climate of the tropical Atlantic in the twentiethcentury simulation of the Community Climate System Model, version 4 (CCSM4). The biases appear in both atmospheric and oceanic components. Mean sea level pressure is erroneously high by a few millibars in the subtropical highs and erroneously low in the polar lows (similar to CCSM3). As a re...

North Pacific and North Atlantic sea-surface temperature variability during the Holocene

Holocene climate variability is investigated in the North Pacific and North Atlantic realms, using alkenone-derived sea-surface temperature (SST) records as well as a millennial scale simulation with a coupled atmosphere-ocean general circulation model (AOGCM). The alkenone SST data indicate a temperature increase over almost the entire North Pacific from 7 cal kyr BP to the present. A dipole p...
