Jetobjecten

Jetobjecten, also known as jet streams, are narrow bands of strong wind in the upper levels of the atmosphere. They are typically found at altitudes between 8 and 14 kilometers (5 to 9 miles) above sea level, within the tropopause, and are characterized by their high wind speeds, often exceeding 100 knots (185 km/h or 115 mph). Jet streams are caused by the difference in temperature between the equator and the poles, which creates a strong pressure gradient and results in the formation of these fast-moving air currents.

Jet streams are not continuous but rather consist of multiple, interconnected streams that can vary in width and intensity. They are typically found in the mid-latitudes, where they are most pronounced during the winter months. Jet streams play a crucial role in weather patterns and climate, as they can influence the movement of weather systems and the distribution of heat and moisture around the globe.

There are two main types of jet streams: the polar jet stream and the subtropical jet stream. The polar jet stream is located at higher latitudes and is associated with the boundary between cold polar air and warmer temperate air. The subtropical jet stream, on the other hand, is found at lower latitudes and is associated with the boundary between warm tropical air and cooler air from the mid-latitudes.

Jet streams can have significant impacts on aviation, as they can either aid or hinder the progress of aircraft. Pilots often use jet streams to their advantage by flying with the wind, which can reduce fuel consumption and increase travel time. Conversely, flying against a jet stream can be more challenging and time-consuming.
