The quantity δθυ sometimes exceeds 3°C, usually because of the advection of warm air from land over cooler water at this site. Thin stable boundary layers result. Unexpectedly, υ∗(V) does not depend systematically on the stratification δθυ even for weak winds. For weak winds, υ∗(V) increases systematically with increasing submeso variations of the wind. The υ∗(V) relationship for a given V is greater in nonstationary conditions. Additionally, this study examines υ∗(V) as a function of wind direction. The υ∗(V) relationship appears to be affected by swell direction for weak winds and advection from land for short fetches.
