UTC = Universal Time Coordinate, the time at Greenwich, England, or 0° longitude. Meteorologists use this to avoid confusion between time zones. mb = millibars, a unit of atmospheric pressure. mps = meters per second. Wind Direction = the direction the wind is coming from. It is measured from north working clockwise: in "meteorological degrees," 0 = North, 90 = East, 180 = South, 270 = West, 360 = North. Relative Humidity = the amount of moisture in the air relative to the amount of moisture the air could possibly hold at that same temperature.
