MP air over the Atlantic can produce winter storms in the Northeast when that air mass is drawn into the region by:. 1) A low pressure system
2) The Jet Stream
3) Zonal Flow

3) Zonal Flow

Explanation:

A jetstream is an area unit that typically slim bands sturdy wind within the higher levels of the atmosphere, and the wind blows from west to east in jet streams. However, the flow naturally moves to the north and south. The flow of these jetstreams follows a specific pattern between hot & cold air, which frequently occurs in winter.

Zonal flow describes how winter storms are being produced within the Northeast region. Coldfront is made during a transition zone, wherever a chilly atmospheric state replaces an atmospheric heat state. Cold air is additionally denser than hotter air. As the dense air shifts into the nice and cozy air region, it forces the friendly and comfortable atmosphere to rise ahead of the cold front quickly.
