A trough is a weather phenomenon characterized by a low pressure area, often elongated in shape, that is associated with clouds, precipitation, and unstable atmospheric conditions. It is commonly found in the vicinity of frontal systems and can lead to the development of storms and severe weather. Troughs are important features in meteorology as they play a significant role in the formation and movement of weather systems.

Explanation
A polar night refers to a period when the sun remains more than six degrees below the horizon all day. This phenomenon occurs in polar regions during winter, where the sun doesn't rise above the horizon for an extended period. As a result, these regions experience continuous darkness throughout the day. This condition is distinct from regions where the sun sets and rises daily, as during a polar night, the sun remains completely below the horizon, resulting in a prolonged absence of daylight.

Explanation
