Large-scale ocean‒atmosphere circulations (LOACs) have a pronounced effect on the near-surface wind speed (NSWS). In this study, we discussed contributions of zonal and meridional flows to NSWS changes identify possible association between Northern Hemisphere Annular Mode (NAM) over eastern China from 1979 2017. Results show that reduction in was mainly dominated by weakening component. NAM has...

-Measurements of the normalized radar cross section (_o) made by the YSCAT nltrawideband scatterometer during an extended deployment on the Canada Centre for Inland Waters (CCIW) Research Tower located at Lake Ontario are analyzed and compared with anemometer wind measurements to study the sensitivity of cr° to the wind speed as a function of the Bragg wavelength. This paper concentrates on upw...

Fossil Fuels are always considered as environmental pollutants. On the other hand, the political and economic situations highly affect the price of these fuels. Offshore wind and wave, as renewable energy sources, represent the better alternatives for electricity generation. Therefore, it is necessary that wind speeds effectively be estimated due to the absence of field measurements of the wind...

1 The transport of the Antarctic Circumpolar Current (ACC) varies strongly across the cou2 pled GCMs (general circulation models) used for the IPCC AR4. This note shows that a 3 large fraction of this across-model variance can be explained by relating it to the param4 eterization of eddy-induced transports. In the majority of models this parameterization is 5 based on the study by Gent and McWi...

The dynamics of equatorial currents are considered in the light of the wind and current measurements at Gan (0.5 S, 73E) reported by KNOX (Deep-Sea Research, 23, 211 221, 1976). For westerly and meridional winds the response of equatorial currents is predominantly local and rapid. It follows that the current reversals observed at Gan are most likely due to changes in the local winds and not to ...

At the Collm Observatory of the University of Leipzig LF D1 low-frequency total re ̄ection nighttime wind measurements have been carried out continuously for more than two decades. Using a multiple regression analysis to derive prevailing winds, tides and the quasi-2-day wave from the half-hourly mean values of the horizontal wind components, monthly mean values of mesopause wind parameters are ...

In this study, wind forecasts derived from the European Centre for Medium-Range Weather Forecasts (ECMWF), National Centers Environmental Prediction (NCEP), Japan Meteorological Agency (JMA) and United Kingdom Office (UKMO) are evaluated lead times of 1–7 days at 10 m multiple isobaric surfaces (500 hPa, 700 850 hPa 925 hPa) over North China 2020. The straightforward multimodel ensemble mean (M...

The annular mode simulated by an atmospheric general circulation model with a zonally symmetric lower boundary is investigated. The annular mode, defined as the leading empirical orthogonal function (EOF) of the zonal-mean surface pressure, has a meridional structure consisting of a north–south dipole, similar to observations. The leading EOF of the zonally varying surface pressure has the same...
