So often March is windy and rainy. What is the explanation behind the cold winds of March?

March winds are created by sharp contrasts of cold air to the north and warm air to the south.

As the Earth rotates toward the sun and daylight increases, the atmosphere begins to warm.

When the two forces meet, warm southern air and cool northern air meet, the differences in temperature creates pressure. This pressure creates wind.
