MSLP = mean sea level pressure, lower means a stronger storm SFMR = instrument to measure winds on the ground/ocean, which are usually weaker than at the plane

MSLP = mean sea level pressure, lower means a stronger storm SFMR = instrument to measure winds on the ground/ocean, which are usually weaker than at the plane's altitude kts = knots = multiply by 1.15 to get wind speeds in miles per hour dropsonde = thing they drop out of the plane to measure wind, temperature, and pressure at different altitudes as it falls Here's how to read wind barbs: http://weather.rap.ucar.edu/info/about_windbarb.html http://weather.rap.ucar.edu/info/about_windbarb.html
