4.0 Forecast Future Conditions at a Projected Point ยป 4.9 Locations of High and Low Pressure

Drawing Question

Using the MSLP field valid for 24 November at 06 UTC, draw the locations of high and low pressure centers.

Instructions: Use the pen to draw the high and low pressure center locations, then click Done.

Tool: Tool Size: Color:

The lowest pressure is found in the area of closed pressure contours, where the values are decreasing towards the center. The high pressures are found to the west and north-east of the low pressure, respectively. High pressure cells are associated with weak pressure gradients (isobars that are farther apart) while low pressures are associated with a stronger pressure gradients (isobars that are closer together).
