fron·to·gen·e·sis

F0339600 (frŭn′tō-jĕn′ĭ-sĭs)n. pl. fron·to·gen·e·ses (-sēz′) Formation or intensification of a meteorological front.

frontogenesis

(ˌfrʌntəʊˈdʒɛnɪsɪs) n (Physical Geography) meteorol the formation or development of a front through the meeting of air or water masses from different origins frontogenetic adj ˌfrontogeˈnetically adv

frontogenesis

the meeting of two masses of air, each with a different meteorological composition, thus forming a front, sometimes resulting in rain, snow, etc.See also: Weather

Frontogenesis

frontogenesis

[¦frən·tō¦jen·ə·səs] (meteorology) The initial formation of a frontal zone or front. The increase in the horizontal gradient of an air mass property, mainly density, and the formation of the accompanying features of the wind field that typify a front.

Frontogenesis

the formation of a front, that is, the transformation of a broad transition zone between two air masses of the troposphere into an abrupt front. Frontogenesis is characterized by an increase in the horizontal temperature gradients and air humidity in the transition zone and by a more or less abrupt change in wind velocity. Kinematic frontogenesis, which is most common, occurs in the field of a wind that brings small particles of air of different temperatures close together. Topographical frontogenesis is sometimes observed as a result of the effect on the air of an abrupt change in the temperature of the underlying surface.
