Jet streams are a particular form of:

Correct option is C

The correct answer is (c) Geostrophic winds.
· Jet streams are a particular form of geostrophic winds.
· Jet streams are narrow, fast-flowing air currents in the upper atmosphere, typically located near the tropopause, which is the boundary between the troposphere and the stratosphere.
· They flow from west to east and are strongest in winter when temperature contrasts between polar and equatorial regions are most significant.
· Jet streams are formed due to a combination of factors, including the Earth's rotation (Coriolis effect), temperature gradients, and pressure differences.
· Jet streams contribute to the transport of heat and moisture across the globe, influencing climate patterns on regional and global scales.
Facts to remember:
· Changes in the strength and position of jet streams can affect temperature gradients, precipitation patterns, and the distribution of weather phenomena like droughts and heatwaves.
· Weather fronts are boundaries between air masses with different temperature, humidity, and density characteristics.
· They are associated with changes in weather conditions, such as precipitation, temperature changes, and shifts in wind direction.
