Insights and Reflection: Cold Front
Today I learned that a cold front is
defined as the leading edge of a cooler mass of air, replacing (at ground
level) a warmer mass of air, which lies within a fairly sharp surface trough of
low pressure. It forms in the wake of an extratropical cyclone, at the
leading edge of its cold air advection pattern, which is also known as the
cyclone's dry conveyor belt circulation. Temperature changes across the
boundary can be as much as 30 °C (54 °F) enough moisture is
present, rain can occur along the boundary. If there is significant instability
along the boundary, a narrow line of thunderstorms can form along the frontal
zone. If instability is less, a broad shield of rain can move in behind the
front, which increases the temperature difference across the boundary. They are
stronger in the fall and spring transition seasons, and weakest during the
summer. When they catch up with the preceding warm front, the portion of
the boundary which does so is then known as an occluded front. Cold fronts occur when a colder air mass replaces a warmer
one. At a cold front, the cold air is behind the warm
air. Because the cold air is denser, it pushes the warm air out of
its way, forcing the warm air to rise into the atmosphere.
I will apply my learning about cold
front in my everyday life so that I am aware about the occurrences that happen
in our weather and environment.
Learning about cold front is important
because it is connected to our weather and environment. In some instances, it
may affect us.
On a larger scale, I will share my
learning about this phenomenon to others because I want them to be committed
and aware to the different things that may happen to our weather, especially
nowadays that there are unexpected things happening.
I need to know more about cold front. I need to learn
other things that are connected to cold front. Because my knowledge is not that
enough.
