Lagrangian drifter paths and length scales in the tropical Pacific warm pool from 1990 to 1991:with application of fractal techniques
Lagrangian drifter paths length scales tropical Pacific warm pool fractal techniques
2009/11/16
This paper presents an analysis of WOCE/TOGA surface drifter paths and its interpretation in conjunction with the west Pacific warm pool water motion. Our interest here lies in the existence of scale ...
Satellite Observations of Mesoscale Eddy Dynamics in the Eastern Tropical Pacific Ocean
Mesoscale Eddy Dynamics Eastern Tropical Pacific Ocean
2009/3/7
Active mesoscale (300 km diameter) eddy formation off the Pacific coast of Central America was observed during February 1976 by a thermal infrared sensor aboard the NOAA 4 satellite. These anticycloni...
A Simple Ekman-Type Model for Predicting Thermocline Displacement in the Tropical Pacific
Ekman-Type Model Tropical Pacific Thermocline Displacement
2009/2/23
A linear model is developed for the near-equatorial zone to estimate wind-driven convergences in the near-surface viscous boundary layer. Using the winds observed during EASTROPAC, an attempt is made ...
The Seasonal Variability in a Model of the Tropical Pacific
The Seasonal Variability Tropical Pacific
2009/2/19
A simple linear model of the tropical Pacific Ocean is used to simulate the oceanic response to time-dependent wind stress forcing. A linear, one-layer, reduced-gravity transport model on an equatoria...
Scales of Thermal Variability in the Tropical Pacific
Thermal Variability Tropical Pacific
2009/2/16
Long-range P-3 aircraft have been used to occupy two 4000 km long sections from 20°N to 17°S along 150 and 158°W in the central equatorial Pacific. The temperature field along these sections was measu...
The Bottom Boundary Layer in the Eastern Tropical Pacific
Bottom Boundary Layer Eastern Tropical Pacific
2009/2/16
Vertical and horizontal structure of near-bottom currents at two locations in the eastern tropical Pacific (9°26′N, 151°17′W; 14°38′N, 125°29′W) have been studied. Low-frequency currents at these site...
Statistical Relations between Ocean/Atmosphere Fluctuations in the Tropical Pacific
trade wind field Tropical Pacific sea surface temperature
2009/2/10
Advanced statistical techniques have been used to conduct a study of the relationships between ocean and atmosphere variables in the tropical Pacific Ocean. The results of the study show that the ocea...
Annual Mean Surface Heat Fluxes in the Tropical Pacific Ocean
Mean Surface Heat Fluxes Tropical Pacific Ocean
2009/2/9
The four components of the long-term annual mean net surface heating of the tropical Pacific Ocean between 30°N and 40°S are calculated and portrayed. These flux elements were derived by using the bul...
El Niño and Tropical Pacific Ocean Surface Temperatures
El Niñ o Pacific Ocean Surface Temperatures
2009/2/7
The spatial and temporal character of El Niño is explored with analyses of tropical Pacific Ocean surface temperatures for the period 1957–76. The data are derived from approximately 5×106 mari...
Interannual Variation in Net Heating at the Surface of the Tropical Pacific Ocean
Tropical Pacific Ocean Net Heating tropical Pacific Ocean
2009/2/5
Interannual variations of net surface heating of the tropical Pacific Ocean are analyzed for the period 1957–76. Special emphasis is given to exploring the relationship between these variations and th...
The Role of Local Heating in Producing Temperature Variations in the Offshore Waters of the Eastern Tropical Pacific
Local Heating Temperature Variations Offshore Waters Eastern Tropical Pacific
2009/2/5
The role of local heating in producing annual and interannual sea-surface temperature variations in the eastern tropical Pacific is studied. Removed from the eastern boundary (122°W), and off the equa...
Wind Direction and Equilibrium Mixed Layer Depth in the Tropical Pacific Ocean
Wind Direction Equilibrium Mixed Layer Depth Tropical Pacific Ocean
2009/1/16
The normal equilibrium state of the tropical Pacific mixed layer is explained by the steady state solution for the maximum vertical penetration of oceanic turbulence generated by local atmospheric for...
The Annual Cycle of Sea Level in the Eastern Tropical Pacific
Annual Cycle Eastern Tropical Pacific Sea Level
2009/1/12
The long period response of sea level on the eastern boundary of the Pacific separates, for linear dynamics, into a remotely forced part mainly due to zonal winds along the equator to the west and a l...
