Best explains difference in jet steam during winter and summer months

• differences in cold and warm air masses are fewer in winter creating stronger jet stream
• differences in cold and warm air masses are fewer in summer creating stronger jet stream current
• differences in cold and warm air masses are greater in winter months creating strong jet current
• differences in cold and warm air masses are greater in summer months creating stronger jet stream currents
