Final answer:
Jet streams are typically found near the boundaries between the major atmospheric cells: the Polar, Ferrel, and Hadley cells, particularly at the 60° and 30° latitudes north or south. Meteorologists use weather maps to track these streams and predict weather patterns.
Step-by-step explanation:
Jet streams are high-speed winds that occur in the upper atmosphere due to significant gradients in air temperature and pressure. These streams are typically found near the boundaries between the Earth's major atmospheric circulation cells: the Polar, Ferrel, and Hadley cells. You would expect to find jet streams occurring at the transitions between these cells, especially between the Polar and Ferrel cells at approximately 60° (marked as 609) north or south of the Equator, and between the Ferrel and Hadley cells at around 30° (marked as 30) north or south.
Meteorologists use weather maps and vector calculus to track and predict such phenomena. Jet streams are crucial for determining weather patterns, as they can influence the movement of storm systems. The concept of high and low pressure regions is central to understanding these dynamics, as air naturally moves from areas of high to low pressure, creating winds.
