Meteorology (Weather)/pressure gradient
QUESTION: does warm air create a cloud and does cold air produce rain in clouds?
ANSWER: Hi Bobby
Up-drafts, rising air, i.e., air (warmer) with "lift" move to higher and colder elevation which then allows for the cold temperatures at the higher levels to cause the water vapor to condense into cloud formations.
Rain is caused by collision of droplets in the clouds.

QUESTION: can a cold front cause high winds and pressure gradients?
A cold front separates cold air from less cold air. Winds are caused by pressure gradients.
Cold fronts some times have "tight" pressure gradients which then are associated with windy conditions.
Strong pressure gradients are as a result of high and low pressure areas; the stronger the systems, along with close proximity, create stronger wind fields.
