which 2 would create a low pressure at the surface? warm temp., cold temp., air moving through a terrain constriction, or air moving out of a terrain constriction.
What is the main reason hail is not associated with tropical thunderstorms: lack of sufficient moisture in the tropical storm, lack of sufficient warmth in the storm ti create up-drafts, lack of sufficient height in the tropical storm to pass the freezing line, or a lack of instability in the tropical storm.
(Straight forward answers, if possible answer with hoices provided please)
To determine which factors create a low pressure at the surface, we need to understand the basics of atmospheric pressure. Air pressure decreases as we move upwards in the atmosphere, and it also varies horizontally due to various factors.
In the first question, the two factors that would create a low pressure at the surface are:
1. Warm temperature: When air is heated, it expands and becomes less dense, resulting in lower pressure at the surface.
2. Air moving out of a terrain constriction: As air flows through a narrow constriction, such as a mountain pass or a narrow valley, it accelerates, creating lower pressure at the surface.
Now, let's move on to the second question about why hail is not associated with tropical thunderstorms. The correct choice is:
1. Lack of sufficient height in the tropical storm to pass the freezing line.
Hail forms when there are strong updrafts in a thunderstorm that carry raindrops upward, allowing them to freeze and accumulate layers of ice. In tropical thunderstorms, the vertical cloud development is generally limited, which means that the storm does not reach significant heights where freezing temperatures exist. Therefore, hail is less likely to form in tropical thunderstorms.
