The paths of two air masses, X and Y, are shown in the diagram below. Air mass X is a cold air mass. Air mass Y is a warm air mass. When the air masses meet, winter storms may be produced. Which of the following most likely contributes to the formation of these storms?

• Cold air mass X moves over warm air mass Y, and evaporation occurs.

• Warm air mass Y moves over cold air mass X, and condensation occurs.

• Cold air mass X mixes with warm air mass Y, and the overall temperature increases.

• Warm air mass Y mixes with cold air mass X, and the overall temperature decreases.
