Wind Speed Retrieval Using Global Precipitation Measurement Dual-Frequency Precipitation Radar Ka-Band Data at Low Incidence Angles

Remote Sensing, 2022
In this study, sea surface wind speed was retrieved using the Global Precipitation Measurement (GPM) dual-frequency precipitation radar (DPR) Ka-band data. In order to establish the Ka-band model at low incidence angles, the dependence of the DPR Ka-band

ENSO effect on the sea surface wind and sea surface temperature in the Taiwan Strait [PDF]

Geophysical Research Letters, 2004
The ERS scatterometer and NOAA/AVHRR data during 1996/4–2000/12 are used to examine the variations of the sea surface wind and sea surface temperature (SST) in the Taiwan Strait (TS) through Empirical Orthogonal Function (EOF) analysis. It is found that the sea surface wind in the TS is southwesterly in summer but northeasterly in the other seasons ...

Parametric Estimation of the Stochastic Dynamics of Sea Surface Winds [PDF]

Journal of the Atmospheric Sciences, 2014
Abstract In this study, the parameters of a stochastic–dynamical model of sea surface winds are estimated from long time series of sea surface wind observational data. The model was introduced by A. H. Monahan, who developed an idealized model from a highly simplified representation of the momentum budget of a surface atmospheric layer ...

Roughness Change Analysis of Sea Surface From Visible Images by Fractals

IEEE Access, 2020
This paper presents an analysis of sea surface roughness from visible images based on fractals features for the first time. We measure fractal dimensions of sea surface images by the methods of box counting, fractional Brownian motion, and area ...

Satellite Oceanographic Data Processing and Analysis: Correlation Between Nino 3.4 Sea Surface Temperature & Sea Surface High and Wind

Indonesian Journal of Earth Sciences, 2022
El Nino Southern Oscillation (ENSO) is an irregular climate oscillation induced by sea surface temperature anomalies (SSTA) in the Equatorial Pacific Ocean. An anomalous warming in this area is known as El Nino, while an anomalous cooling bears the name

Altimeter Estimation of Sea Surface Wind Stress for Light to Moderate Winds [PDF]

Journal of Atmospheric and Oceanic Technology, 1997
Aircraft altimeter and in situ measurements are used to examine relationships between altimeter backscatter and the magnitude of near-surface wind and friction velocities. Comparison of altimeter radar cross section with wind speed is made through the modified Chelton-Wentz algorithm.

Derivation of Sea Surface Wind Directions from TerraSAR-X Data Using the Local Gradient Method

Remote Sensing, 2016
Derivation of sea surface wind direction is a key step of sea surface wind retrieval from spaceborne Synthetic Aperture Radar (SAR) data. This technical note describes an implementation of the Local Gradient (LG) method to derive sea surface wind ...

A two-parameter wind speed algorithm for Ku-band altimeters [PDF]

, 2002
Globally distributed crossovers of altimeter and scatterometer observations clearly demonstrate that ocean altimeter backscatter correlates with both the near-surface wind speed and the sea state.

A relation between the wind friction velocity and the sea surface microwave scattering

Ciencias Marinas, 2002
 A simple recursive algorithm for the estimation of the friction velocity as a function of the air-sea temperature difference and the wind speed measured at 10-m height above the sea surface, without needing of drag coefficient, is presented.

The Impact of Surface Waves and Spray Injection Velocities on Air–Sea Momentum and Heat Fluxes

Atmosphere, 2023
Surface waves and sea spray play a significant role in air–sea fluxes in high winds. The present study used a marine atmosphere surface layer (MASL), which couples the traditional Monin–Obukhov similarity theory, sea spray generation function, the ...
