“Gradient” wind impact on breezes: Breeze Index
•                                  
•   wind = DP/(2rRDS) = 589 x  D P/D S     sin (lat)
•        Wind Speed = 22.9 kts
• 
•         Breeze Index = Wind Speed2
•           DT
DDT is the air temperature difference from lake to land (F)
D Over lake air temp = watertemp +10F
DIf BI is greater than 14, there will
Dbe no breeze…. Here BI = 26, no breeze
