You could perhaps have some sort of filter material stuffed up into the ridge vent from the inside -- something which still allows airflow but stops the snow from entering.
Also, do you have enough intake vents? A lot of times, if you have adequate intake air, the airflow pushing out of the ridge vent will prevent things from coming in.

During dry snow storms snow enters the building through the ridge vent. The top of the metal panels from each side of the roof are about 1&1/2 inches apart under the ridge cap , but the snow blows in the building if it is a dry snow , is there any way to prevent this? is there
any product that can stop the snow but still allow the roof to vent ?

Todd is absolutely correct. There should be some sort of filter or mesh (Cobra vent, etc) at the ridge, but the more pressing issue should be to have a balanced system.
In these applications, it make better sense to have it 60/40 split between intake/exhaust air as well.
