RESEARCH


SST Animations for CP and EP El Nino Events
Animations of SST anomalies are displayed and contratsed for Eastern-Pacific (EP) type and Central-Pacific (CP) type of El Nino and La Nina events. [more]

Two Types of El Nino: Central-Pacific El Nino and Eastern-Pacific El Nino
There are two types of El Nino/La Nina: an eastern-Pacific (EP) type and a central-Pacific (CP) type. The CP and EP El Nino/La Nina have different patterns, evolution, teleconnections, and generation mechanisms.... [more]

A New Global Parallel and Coupled Ocean-Atmosphere GCM
A new global, high-resolution, and parallel coupled atmosphere-ocean GCM has been developed under a joint project between UC and Los Alamos National Laboratory. ... [more]
View QuickTime or AVI animations of SST in year 8 and 9.

ENSO Simulation, Dynamics, and Prediction
The CGCM Developed by Prof. Yu is one of the models able to produce ENSO-like climate variability with reasonable frequency and amplitude. ...[more]
View the simulated ENSO cycle here.

ENSO-Monsoon Interactions
Our investigations focus on how the mutual influences of ENSO and Asian Monsoon are established and how the Indian Ocean might affect these influences. ... [more]

Indian Ocean Zonal Mode
We are able to simulate the Indian Ocean zonal mode (IOZM) in CGCM integrations with and without ENSO events in the Pacific. The generation mechanism of IOZM and its relationship with ENSO are studied. ... [more]

Pacific Decadal Oscillation (PDO)
Pacific Decadal Oscillation (PDO) is believed to contribute to the decadal changes in ENSO activity. We study PDO's generation and modulation mechanisms using CGCM simulations. ... [more]

Tropical Instability Waves (TIW)
Both CGCM simulations and satellite observations are used to study the seasonal and interannual variations of Tropical Instability Waves (TIWs) and their coupling with the atmosphere. ... [more]

Tropical-Extratropical Interactions
Evidence is presented that ENSO in the tropics can force a anomaly SST dipole off the coast of the California through surface heat flux. ... [more]

Cloud-Radiation Feedback
Impacts of high-level clouds and marine boundary layer stratus on tropical atmosphere-ocean system are demonstrated with CGCM experiments. ...[more]

Jetstream and Stormtrack Vacillation
A slow vacillation of jetstram/stormtrack location and strength is shown to be self-maintained by the interactions with the embedded baroclinic waves. ...[more]

Regional Climate Variations
We investigate the roles of oceanic influence, land-surface memory, and internal atmospheric dynamics in forcing interannual variability of North American Monsoon and the associated continental-scale precipitation mode. ...[more]

Central America Gap Wind and Eastern Pacific Warm Pool
The mechanical and thermal impacts of Central America gap winds on the annual cycle of sea surface temperature in the eastern Pacific warm pool are examined with observations and a series of regional ocean model experiments. ...[more]
