Subtropical Forcing of Tropical Pacific Climate and Decadal ENSO Modulation
The relative impact of the subtropical North and South Pacific Oceans on the tropical Pacific climate mean state and variability is estimated using an ocean–atmosphere–sea ice coupled general circulation model. Tailored experiments are performed in which the model is forced by idealized sea surface temperature anomalies (SSTAs) in the subtropics of both hemispheres. The main results of this stu...
متن کاملGlobal Energy and Water Cycle Experiment GEWEX Modelling and Prediction Panel ( GMPP ) Studies Advancing Parameterization
GMPP Activities Highlighted in this Issue GPCI analyzes weather and climate models along a cross section of the Pacific Ocean. Histograms of total cloud cover versus latitude along the GPCI cross section for June–July–August 1998 from the UKMO/HadGAM model, ISCCP and the NCAR/CAM3 model. These show that some climate models (e.g., UKMO/HadGAM) exhibit a quasi-bimodal structure with cloud cover b...
متن کاملCloud Products for Weather Prediction and Climate Modelling
The EU-FP4 project Cloudmap aimed to estimate new cloud-top products (heights, type, optical thickness, effective droplet size), especially for cirrus and contrail clouds from existing and new sensors, using three different techniques (brightness tem¬ perature with C02 slicing method, stereo-scopy and Oxygen A-band). These cloud-top products were validated using airborne sensor underflights, mu...
متن کاملOcean noise in the tropical and subtropical Pacific Ocean.
Ocean ambient noise is well studied in the North Pacific and North Atlantic but is poorly described for most of the worlds' oceans. Calibrated passive acoustic recordings were collected during 2009-2010 at seven locations in the central and western tropical and subtropical Pacific. Monthly and hourly mean power spectra (15-1000 Hz) were calculated in addition to their skewness, kurtosis, and pe...
متن کاملOptimizing Computations in Weather and Climate Prediction Models
To meet the challenge of developing a comprehensive weather and climate prediction model which can give realistic scenarios for many time scales, more computer power than is currently available will be needed. One possibility for alleviating this shortcoming is to increase the integration timestep. We propose and test several methods which may prove useful. One procedure is an expansion of the ...
