Frontogenesis (original) (raw)
Frontogenesis is a meteorological process of tightening of horizontal temperature gradients to produce fronts. In the end, two types of fronts form: cold fronts and warm fronts. A cold front is a narrow line where temperature decreases rapidly. A warm front is a narrow line of warmer temperatures and essentially where much of the precipitation occurs. Frontogenesis occurs as a result of a developing baroclinic wave. According to Hoskins & Bretherton (1972, p. 11), there are eight mechanisms that influence temperature gradients: horizontal deformation, horizontal shearing, vertical deformation, differential vertical motion, latent heat release, surface friction, turbulence and mixing, and radiation. Semigeostrophic frontogenesis theory focuses on the role of horizontal deformation and shear

(en) Frontogenese is het ontstaan van fronten, of in wijdere zin het verscherpen of activeren van een bestaand front. Dit treedt op bij grenzende luchtsoorten, warme en koude zeestromen, sneeuwgrenzen op het vasteland en aan de grens van continenten en oceanen. Frontolyse is het tegenovergestelde hiervan; dit is het oplossen of verzwakken van fronten. Convergerende luchtsoorten komen vooral voor langs de uitstromingsas in een zadelgebied. De verschillen tussen luchtsoorten kunnen in de zomer toenemen doordat een koufront van zee het verhitte vasteland nadert. In de winter vermeerdert het verschil wel doordat een warmtefront van zee het sterk afgekoelde vasteland nadert. (nl) |
