### location | locality:

Front
* Most fronts affect weather
  - produce precipitation
* Some fronts bring precipitation
  - thunderstorms
  - have few clouds when the air is very dry
  - produce no precipitation and little cloudiness, although there is usually a wind shift
* also help to lift and cool the air, creating clouds and precipitation.
* are appearances
  - as large as real weather systems, and can be several thousand kilometres long and wide
* are boundaries between air currents of contrasting temperature and humidity
  - masses of different temperatures
  - guided by winds aloft, but they normally move at lesser speeds
  - identified by change of temperature based upon their motion
  - lines marking the leading edge of a change in air mass or temperature
  - located on the transition between different air masses
  - nothing more than areas where two different air masses meet
  - positions
* are regions of strong horizontal density gradients in the ocean
  - the atmosphere where air masses meet and slide over one another
  - sides
  - spheres
* are the boundaries between air masses, marking the edges of individual air masses
  - two air masses
  - locations where most of the cyclone's precipitation occurs
  - principal cause of significant weather
  - ubiquitous in the ocean, especially in the coastal zones
  - usually detectable at the surface in a number of ways
* are zones of temperature contrast accompanied by wind shifts and pressure kinks
  - transition between two different air masses
* bring stormy weather
* contain materials.
* define the boundaries between air masses.
* develop in which warm, moist Atlantic air is pushed up over cooler air.
* enhance capability.
* generally move from west to east and are associated with low pressure systems.
* mean areas with a noticable increase or decrease in temperture, i.e. warm and cold fronts.
+ Weather front: Meteorology
  * Cold fronts may feature narrow bands of thunderstorms and severe weather, and may on occasion be preceded by squall lines or dry lines. Warm fronts are usually preceded by stratiform precipitation and fog. The weather usually quickly clears after a front passes. Some fronts produce no precipitation and little cloudiness, although there is usually a wind shift.

Cold front
* Most cold fronts affect weather
  - bring weather
* Some cold fronts affect countries.
* Some cold fronts bring heavy thunderstorms
* Some cold fronts have slopes
  - steep slopes.
  * A 'cold front' meteorological word that is used to describe the movement of a cooler airmass into an area of warmer air. University of Illinois. The air with greater density moves under the less dense warmer air, lifting it, which can cause a line of showers and thunderstorms, or a squall line to form when there is sufficient moisture. This upward motion causes lowered pressure along the cold front. Cold fronts can also move up to twice as fast as warm fronts
* are fronts
  - much more frequent and vigorous over southern Australia than elsewhere
  - often coloured blue
  - stronger in the fall and spring transition seasons and weakest during the summer
* bring lower temperatures and can create narrow bands of violent thunderstorms
  - cause air to rise as well
  - produce dramatic changes in the weather
* have a tendency to create tougher fishing conditions.
* move fast, about twice as fast as a warm front.
* occur when cold air moves into a region previously occupied by warm air.
* ride down from Canada on a northwest wind.
* slow down the fish metabolism in Japan as well as in Italy.
* sweep down from the north, pushing boats south with strong northwest to northeast winds.
* tend to be associated with the most violent weather among all types of fronts.
* tend to move faster than all other types of fronts
