Which air masses have the greatest effect on weather conditions in much of the US
continental polar and maritime tropical
The weather behind a cold front is dominated by
What type of front forms when the surface position of the front does not move
Along a front which type of air is always forced upward
What stage happens first in the life cycle of a middle-latitude cyclone
AIR Flows counterclockwise
What are the major air masses that influence the weather in the Unites states
There are four types of air masses that influence weather in the
United States. These are continental polar, maritime polar,
continental tropical, and maritime tropical.
What kind of front is created when a cold front overtakes a warm front
It's an occluded front.
occluded front.
When a cold front overtakes a warm front, the warm air mass is lifted entirely off the ground and an occluded front forms.
This is an occluded front.
An occluded front occurs
Which air mass often originates as a different air mass in Siberia and is subsequently altered
Wave impact and pressure cause
Hurricanes produce sustained winds of at least
Hurricanes produce sustained winds of at least 74 mph (119
km/h).
In which type of front is the flow of air on both sides of the front almost parallel to the line of the front
A warm front
^wrong answer^
During which stage of a thunderstorm does rain begin to fall
The stage of a thunderstorm that rain begins to fall is when the clouds begin to turn black and during and after the lightning strikes.
What kind of shape is associated with a middle-latitude cyclone
Middle-latitude cyclones (also called extratropical lows) often
have a comma shape.
Violently rotating column of air
A violently rotating column of air is called a tornado.
How does surface air flow in a middle latitude cyclone in northern hemisphere
Convergent Counterclockwise
Which is not true about a wave in the open ocean
The waves in the open ocean are usually caused by the friction
of the winds over the open ocean of water. The waves in the ocean
vary in strength and size depending with the speed of wind and the
friction with the surface of water.
What forms where warm air moves toward cold air
Tornadoes are most frequent from
Tornadoes are most frequent from April through June.
What is the first sign of an approaching warm front
What is the shape of a middle-latitude cyclone
Mid-latitude cyclones are typically comma-shaped.
Surface currents are caused by friction between which two elements
the ocean surface and wind
Where are hurricanes least likely to happen
Hurricanes, Cyclones and Typhoons (they are all the same thing)
dissiape enormous amounts of energy. On Earth this energy comes
from the Sun and the Sun;s energy stored in Sun warmed waters in
the the Tropics. Therefore Hurricanes are a feature of tropical
oceanic regiones.
Thus the poles and the centre of continents are areas where
hurricanes are least likely to happen.
