When contrasting air masses lie side by side,the narrow zone of discontinuity, separating the two masses is called a front.So when cold airmass meets and displaces a warmer airmass,the front that is formed is called cold front.
Along a cold front, heavy rain or snow,frequent thunderstorms, severe turbulance, line squalls and heavy icing may occur.Along the front a well marked wind shift of 45 degrees to 180 degrees may be noticed.The front may have a slope of 1/40 to 1/80.Cloud systems precede the cold front upto over 100 miles ahead and gusty winds occur in the rear.The rain belt may be 50 to 100 miles wide.Occasionally tornados may also form.

An area of low pressure will probably form. Warm air will rise and start the creation of thunderstorms. Hurricanes don't occur in changing airmasses. If the upper level winds are strong enough, the air inside the thunderstorm will start to rotate: at first horizontally, then if strong enough rotation, vertically creating tornadoes. Hope this helps.

Usually just a low pressure system. This could spawn tornadic activity. Hurricane.....no way. Hurricanes form in the same airmass, not an interaction of two. Cold and warm air doesn't mix, and dry and wet air doesn't mix. So both those factors together and it can get pretty nasty sometimes. But yeah, the two airmass colliding will give you your basic, run-of-the-mill frontal system.

An easterly wind oftentimes brings dry climate and extreme rigidity. this means very chilly air interior the wintry climate. Snow oftentimes arrives while the wind swings around to the west bringing warmer moister air which turns to snow while it meets the chilly air. The snow would not oftentimes final long by using fact the air warms up with a westerly wind.

Thunderstorms. Sometimes severe ones. No hurricanes but possible tornadoes.

when they mix the cold air meets a warm are then cold air relps over the warm creating a tornodo, hurricane, or a typoon
