What is typically true about the strength and location of the jetstream in the summer?

In the summer, the jet stream generally becomes weaker and shifts farther north compared to its position in the winter months. This phenomenon occurs due to the increased solar heating of the Earth's surface, which leads to warmer temperatures across the continental regions. Warmer air results in a less pronounced temperature gradient between the equator and the poles, which in turn weakens the jet stream. Additionally, the position of the jet stream tends to migrate northward because the polar regions are not as cold as they are in winter, resulting in a more laid-back and weaker jet stream during the summer season. This impacts weather patterns, as a weaker jet stream leads to less dynamic weather systems and generally more stable atmospheric conditions.
