Oceanographic Conditions of Bowhead Whale Habitat

Hi, I am a student of St. Mark Cathlic School. I read your journal 'Who'll Stop The Rain.' I have a Question about it. Do you know what caused the weather to shift like it did?

changes where you live. Different air masses move into an area and the
front or boundary that separates these air masses causes the air to
rise. Rising air is cooled and can't hold the water as well as the
lower, warmer air and "Walla!" Condensation occurs which can lead to
precipitation. Remember that Earth is not the same temperature
everywhere, it's warmer at the equator and colder near the poles.
Different temperatures causes differences in pressure which causes the
air to move horizontally. Air always moves from a high pressure area to
a low pressure area and as the air moves it brings the temperature and
humidity of a source region with it.
