15. 3,4 Name two conditions to expect during a Nor’ Easter. Why would you expect to receive a lot of rain or snow? High winds from the NE/ counterclockwise rotation

16. 4,1 Two major difference between cyclones and anticyclones are.. What type of weather is a cyclone generally associated with? Direction of their winds/ wet, cloudy

17. 4,2 Name 3 “ingredients” needed for a hurricane to form Warm ocean waters, low pressure, winds

18. 4,3 What is an isobar? Name one unit used to measure air pressure and the instrument that does it Equal pressure, mb or inches of mercury/ barometer

19. 4,4 Describe the type of pressure that is over us right now. How do you know? Tomorrow it is going to be 33 degrees out. What type of front will be moving through tonight? What type of observable weather might we expect?
