Cold fronts are depicted by
blue line with triangles pointing in the direction of motion
. Cold fronts demarcate the leading edge of a cold air mass displacing a warmer air mass. Phrases like “ahead of the front” and “behind of the front” refer to its motion.
What are the symbols of fronts?
- A stationary front line is indicated by blue triangles on one side of the line alternating with red semi-circles on the opposite side of the line. …
- A cold front is a front that is moving in the direction of the warmer air.
What symbol shows stationary front?
A stationary front is represented by
alternating blue and red lines with blue triangles pointing towards the warmer air and red semicircles pointing towards the colder air
. A noticeable temperature change and/or shift in wind direction is commonly observed when crossing from one side of a stationary front to the other.
What is a cold front example?
A cold front is defined as the transition zone where
a cold air mass is replacing a warmer air mass
. In the example below, temperatures ahead of the cold front are 55 and 62 degrees while behind the front, the temperatures are lower, 31 and 28.
What are the four weather symbols?
- Sunny skies.
- Partly cloudy.
- Cloudy.
- Windy.
- Rainy.
- Fog.
- Snow, and.
- Thunderstorms.
What are the weather front symbols?
The front marks the leading edge of the cold air. The
blue triangles always point in
the direction that the front (and the cold air) is going. A red line with half-circles on one side signifies a warm front. A warm front shows the leading edge of warmer air trying to replace a colder air mass.
What is a stalled front?
A stationary front is a non-moving
(or stalled) boundary between two air masses
, neither of which is strong enough to replace the other. They tend to remain essentially in the same area for extended periods of time, usually moving in waves.
What symbol represents an occluded front?
Symbolically, an occluded front is represented by
a solid line with alternating triangles and circles pointing the direction
the front is moving. On colored weather maps, an occluded front is drawn with a solid purple line.
What is the edge of a cold or warm front called?
In other words, a
cold front
is right at the leading edge of moving cold air and a warm front marks the leading edge of moving warm air. When two air masses meet together, the boundary between the two is called a weather front.
What are characteristics of a cold front?
Cold Fronts
moisture content (dew point) changes dramatically
.
wind shift (direction and speed) pressure trough
(pressure tendency is useful!!!) often cloudy/showers/thunderstorms/sometimes severe.
What makes a cold front?
Cold fronts form
when a cooler air mass moves into an area of warmer air in the wake of a developing extratropical cyclone
. The warmer air interacts with the cooler air mass along the boundary, and usually produces precipitation. Cold fronts often follow a warm front or squall line.
What is a cold front kid definition?
A cold front is a meteorological word that is
used to describe the movement of a cooler air mass into an area of warmer air
. … This upward motion causes lowered pressure along the cold front. Cold fronts can also move up to twice as fast as warm fronts.
What is the squall symbol?
Squall lines are depicted on National Weather Service surface analyses as an
alternating pattern of two red dots and a dash labelled “SQLN”
or “SQUALL LINE”.
How do you read wind symbols?
The
dot end
of the staff is where the wind is blowing to, while the top of the staff shows the direction from which the wind is coming. The top row of wind barbs in the figure to the right all indicate a north wind. The dot is to the south and the top of the wind barb staff is to the north.
What is the weather symbol for wind?
Wind direction is represented by
an arrow pointing in the direction
from where the wind is coming. The wind speed is denoted by “feathers” on the wind arrow, a short feather indicating 5 knots, a larger one 10 knots, a long and short one 15 knots and so on.
What are 4 types of fronts?
- Cold Front. A side view of a cold front (A, top) and how it is represented on a weather map (B, bottom). …
- Warm Front. …
- Stationary Front. …
- Occluded Front.
