Machine Learning-Based Estimation of Tropical Cyclone Intensity from Advanced Technology Microwave Sounder Using a U-Net Algorithm

open access: yesRemote Sensing, 2023
A U-Net algorithm was used to retrieve surface pressure and wind speed over the ocean within tropical cyclones (TCs) and their neighboring areas using NOAA-20 Advanced Technology Microwave Sounder (ATMS) reprocessed Sensor Data Record (SDR) brightness ...

Ku-Band Radar Altimeter Surface Wind Speed Algorithm [PDF]

open access: yesMarine Geodesy, 2012
A surface wind speed retrieval algorithm from Ku-band radar altimeter backscatter coefficients is presented. It was derived using two-months of ENVISAT altimeter backscatter data collocated with ECMWF model and in situ wind speeds and was extensively verified for ENVISAT, ERS-2, and Jason-1/2 against model and in situ wind data.

Examination of Surface Wind Asymmetry in Tropical Cyclones over the Northwest Pacific Ocean Using SMAP Observations

open access: yesRemote Sensing, 2019
Tropical cyclone (TC) surface wind asymmetry is investigated by using wind data acquired from an L-band passive microwave radiometer onboard the NASA Soil Moisture Active Passive (SMAP) satellite between 2015 and 2017 over the Northwest Pacific (NWP ...

What can surface wind observations tell us about interannual variation in wind energy output?

open access: yesWind Energy, 2022
The past decade of wind power growth was supported by capacity factor improvements and associated cost reductions. But are higher capacity factors a technology success story or, as suggested by recent research, has the influence of technology been ...

Wind field and pressure characteristics on wind turbine surface under moving thunderstorms

open access: yesEnergy Reports, 2023
Based on computational fluid dynamics and large-eddy simulation technologies, a numerical simulation method of a moving thunderstorm field is established by considering the impinging jet model.

Research on Inversion of Sea Surface Wind Speed from GF-3 Cross Polarization Data [PDF]

open access: yesJisuanji gongcheng, 2020
The inversion of the ocean surface wind field with single-polarized Synthetic Aperture Radar(SAR) data has a complex operational model.The use of cross polarization SAR images to invert the ocean surface wind has become a hot topic in research.Taking the

Coupled ocean–atmosphere interactions between the Madden–Julian oscillation and synoptic-scale variability over the warm pool [PDF]

open access: yes, 2005
A principal component analysis of the combined fields of sea surface temperature (SST) and surface zonal and meridional wind reveals the dominant mode of intraseasonal (30-70-day) co-variability during northern winter in the tropical Eastern Hemisphere ...

Object-Based Analog Forecasts for Surface Wind Speed [PDF]

open access: yesMonthly Weather Review, 2017
Analogs are used as a forecast postprocessing technique, in which a statistical forecast is derived from past prognostic states. This study proposes a method to identify analogs through spatial objects, which are then used to create forecast ensembles.

Effect of Varying Wind Intensity, Forward Speed, and Surface Pressure on Storm Surges of Hurricane Rita

open access: yesJournal of Marine Science and Engineering, 2021
Hurricane storm surges are influenced by several factors, including wind intensity, surface pressure, forward speed, size, angle of approach, ocean bottom depth and slope, shape and geographical features of the coastline.

Analysis of the influence of the wind speed profile on wind power production

open access: yesEnergy Reports, 2022
The characterization of wind speed and its variability at a site is important for wind resource assessment. The most readily available wind measurements are at 10 m above ground level.
