polar; subtropical
The warmer temperatures in the northeast during winter could be due to fluctuations in weather patterns, such as the presence of a strong jet stream bringing warmer air from the south or the influence of climate change leading to overall warmer conditions. Atmospheric conditions and weather systems can vary from year to year, leading to unusual warmth in certain regions during winter.
The jet stream
When a tropical air mass moves in from the south, it typically brings warm, humid conditions to the area. This influx of moisture can lead to increased cloud cover and the potential for precipitation, such as rain or thunderstorms. The temperature usually rises, creating a more oppressive and muggy atmosphere. Overall, the weather becomes noticeably warmer and more unstable, often resulting in changes in local weather patterns.
A continental jet-stream travels parallel to the equator - a polar jet-stream travels in a north/south direction.

When the jet stream moves south to North Carolina, it can lead to significant changes in weather patterns, including cooler temperatures and increased precipitation. This shift may result in enhanced storm activity, as the jet stream often influences the development of low-pressure systems. Additionally, if the jet stream remains in this position for an extended period, it could create prolonged periods of unsettled weather, including rain or even winter storms, depending on the season.
The jet stream is a fast-flowing, narrow air current in the upper atmosphere that influences the movement of weather systems. Changes in the jet stream's position and strength can impact the direction and speed of surface winds. The jet stream's meandering path can cause shifts in the pressure systems on the ground, which in turn affect wind patterns at the surface.
Downhill would be the only sure answer. Depending on the river they will flow in many different directions during the course of their travels. The Nile moves North, the Mississippi moves South, the Amazon goes mostly East.
In general, its cooler (at least north of the jet).
During a cold spell in Minnesota, you can expect temperatures to drop well below freezing, often reaching negative double digits. This extreme cold is typically accompanied by strong winds, leading to dangerous wind chills that can make it feel even colder than the actual temperature. Additionally, snowfall may occur during a cold spell, further contributing to hazardous conditions.
The primary jet stream affecting weather in South Africa is the subtropical jet stream. This jet stream typically flows at higher altitudes and influences weather patterns, particularly during the winter months, by steering systems that can bring rainfall or dry conditions. Its position and strength can lead to significant variations in temperature and precipitation across the region. Additionally, the polar jet stream can also impact southern Africa, especially during transitional seasons.
The gulf stream moves warm water from the south up t the north and west thus keeping europs climate much warmer and more mild then it would be without it.
