Record 4 2015-04-16

English

Subject field(s)
  • Atmospheric Physics
CONT

If the strong horizontal temperature gradient associated with a front maintains a near constant direction through a deep layer of the atmosphere, the thermal wind component will have a constant direction through successively higher layers. As this component is added consecutively to the actual wind at each level, the wind will increase markedly with height. This is how the very strong winds of frontal jet streams originate.

French

Domaine(s)
  • Physique de l'atmosphère
CONT

Si le fort gradient de température horizontal associé à un front conserve une direction presque constante à travers une couche profonde de l’atmosphère, le vent thermique a une direction constante dans des couches de plus en plus élevées. À mesure que cette composante s’ajoute consécutivement aux vents réels à chaque niveau, le vent augmente nettement avec l’altitude. C’est ainsi que naissent les très forts vents des courants-jets frontaux.

Record 7 2005-04-11

English

Subject field(s)
  • Meteorological Forecasting, Data Measurement and Analysis
  • Atmospheric Physics
CONT

The geostrophic wind approximations are broken into its two horizontal components. The "U" component represents the east-west component of the wind while the "V" component represents the north-south component. The two formulas for the U and V component of wind are as follows... The minus sign in front of the U component answer indicates an easterly component to the wind, or in other words, a wind that blows from east to west. A positive U component would mean that the wind is blowing from west to east.

The "U" component represents the east-west component of the wind while the "V" component represents the north-south component. The two formulas for the U and V component of wind are as follows... The positive V component answer indicates a southerly component to the wind, or in other words, a wind that blows from south to north. A negative V component would mean that the wind is blowing from north to south.

Subject field(s)
  • Atmospheric, Climatic and Meteorological Phenomena
DEF

The rainfall which is deflected, by strong winds, from its normal vertical fall and is intercepted by the walls of buildings.

CONT

Numerical calculation of driving rain on buildings. Rain, which is given a horizontal velocity component by the influence of wind, is termed wind-driven or driving rain. Driving rain is one of the main sources to the amount of moisture a building is exposed to, and thereby contributes to the processes deteriorating the building envelope. Knowledge about the exposure of a building to driving rain is needed in order to minimise the deteriorating processes, and thus contributes to ensure a satisfactory performance of the building design.

Subject field(s)
  • Atmospheric, Climatic and Meteorological Phenomena
CONT

Driving rain is rain that is carried by the wind and driven onto the building envelope (façades and roofs). It is a complex phenomenon of falling raindrops in a turbulent flow of wind around a building. It is one of the important climatological factors which determine long-term use and durability of building envelopes.
