Question 3
What high-impact weather would you expect to occur from the cold front and cut-off low in area C? Choose all that apply.
The correct answers are C and D.
By nature, mid-latitude systems are associated with very cold temperatures due to cold air advection from the polar and subpolar regions. The area of convergence of this cold air with warmer sub tropical air gives rise to instability, which results in showery conditions and associated heavy rainfall and reduced visibility. For the aviation industry, the change in wind speed and direction with height results in turbulence, while low freezing levels in the vertical result in icing.
