The hourly mean wind speed in the northern part of the North Sea may reach 38–40 m/s, which is about 20% greater than the value found in the southern North Sea. On the other hand, wave heights are likely to exceed the 30 m level in the northern North Sea, which is about twice ...
The diabatic method has been tested using a 4-month data-set consisting of wind speeds measured at heights of 18 and 70 m and temperatures of the air and the sea water. The mean wind speed measured at a height of 70 m over this period was 9.6 m s 1. Using the diabatic method the...
Charnock's Roughness Length Model and Non-dimensional Wind Profiles Over the Sea An analysis tool for the study of wind speed profiles over the water has been developed. The profiles are analysed using a modified dimensionless wind spee... A Peña,SE Gryning - 《Boundary Layer Meteorology》 ...
The North Sea 10-m wind speed (WS10) climate is compared and related to circulation patterns based on the sea level pressure (SLP) extracted from three reanalysis and one high-resolution model dataset. The mean magnitude and the trends of WS10 depend considerably on the selected reanalysis. ...
Many of the factors that weaken storms over land could begin to act when they are still at sea, yet prelandfall intensity change remains poorly documented. This study examined the consistency of prelandfall changes in tropical cyclone intensity throughout the North Atlantic Ocean from 1950 to ...

As the air spirals upward it conserves its angular momentum, which depends on the distance from the centre of the cyclone and on the wind speed around the centre. Since the wind speed decreases with height, the air must move farther from the centre of the storm as it rises. When up...
In Figure 4, it can be found that the wind speed at each of the 16 directions also shows seasonal variation in the four seasons. The wind speed in summer is lower than in the other seasons. In the Bohai Sea, the higher wind speeds are often associated with northeasterly, northwesterly...
