Advantages

• Gives what a soaring pilot wants to know

• Uses forecast conditions (often PM atmosphere not same as in AM)

• Shows local variations (such as those due to terrain)

• Shows conditions far away (for XC)

• Can predict some things a sounding cannot (sfc. heating ⇒ thermal strength, convergence, ...)

• Using viewer, mouse click on blipmap will display full forecast sounding for that specific location
