appearance as argument number 1

(documentation surfaceWindDirection EnglishLanguage "(surfaceWindDirection ?PLACE ?DIRECTION) means that at ?PLACE the wind is coming from the compass point ?DIRECTION. For example, (surfaceWindDirection SanFranciscoBay Northwest) means that the wind in San Francisco Bay is coming from the Northwest. The wind is within 500 feet of Earth's surface.")

Weather.kif 166-174

If a directional attribute is a surface wind direction of an object,
then there exist a process and another object such that the process is an instance of wind and the other object is an instance of region and the process is partly located at the object and the process originates at the other object and the other object is the directional attribute to the object

consequent

(=> (and (instance ?ZEPHYR WindFlow) (measure ?ZEPHYR (VelocityFn ?DIST ?TIME ?PLACE ?DIR-TOWARD)) (oppositeDirection ?DIR-TOWARD ?DIR-FROM)) (surfaceWindDirection ?PLACE ?DIR-FROM))	Weather.kif 182-187	If a physical is an instance of wind flow and the measure of the physical is a length measure per a time duration in a region in the direction an entity-TOWARD and the entity-FROM is an opposite direction of the entity-TOWARD, then the entity-FROM is a surface wind direction of the region
(=> (and (surfaceWindVelocity ?PLACE ?SPEED ?DIR-TOWARD) (oppositeDirection ?DIR-TOWARD ?DIR-FROM)) (surfaceWindDirection ?PLACE ?DIR-FROM))	Weather.kif 176-180	If an object is surface wind velocity a physical quantity for an entity-TOWARD and the entity-FROM is an opposite direction of the entity-TOWARD, then the entity-FROM is a surface wind direction of the object
