• RESULTS
• Offshore synoptic-scale flow of 3-5 m/s created
  strongest sea breeze front.
• These fronts most intense during early afternoon
  within 15 km of the coastline.
• Average sea breeze start time 1730 UTC
• Onshore synoptic-scale flow created the weakest
  sea breeze fronts.
• These fronts strengthen late in the afternoon 20
  km inland.
• Average sea breeze start time 1330 UTC
• Coast parallel westerly flow 3-5 m/s created an
  intense sea breeze front 20 km inland
• Strength of the sea breeze front a balance
  between convergence at the sea breeze front
  (frontogenetic) and turbulent mixing of sea
  breeze air behind the front (frontolytic)
