WebFinally, the cloud ice threshold was identified as promising tuning parameter. This parameter controls the Bergeron–Findeisen process, which explains the growth of ice crystals at the expense of cloud droplets in mixed-phase clouds due to lower vapor pressures over ice than over water at subfreezing temperatures. WebDec 9, 2024 · In the troposphere, the normal ice crystal shape that forms from direct deposition of water vapor is hexagonal (see INFO Box at left). The particular hexagonal shape that grows depends on temperature and supersaturation (Fig. 7.12). These shapes are called habits.

This process is of particular … Webcrystals in order to enhance the Bergeron process. This is done to either enhance precipitation, or to disperse fog. It can be somewhat successful on a small scale (such as trying to clear fog at an airport). Warm clouds are seeded with salt particles in an effort to get a few large drops to form to initiate the collision-coalescence process. hawkes cycles birminghamWebIce-crystal (or Bergeron) process The ice-crystal process is important in what latitudes? middle & high What kind of clouds are able to extend upwards into regions where air temp below freezing?

"WebMar 6, 2024 · The Bergeron process often results in precipitation. As the crystals grow and fall, they pass through the base of the cloud, which may be above freezing. This causes the crystals to melt and fall as rain. There also may be a layer of air below freezing below the cloud base, causing the precipitation to refreeze in the form of ice pellets.
