Estimate lifted condensation level (cloud base) from surface data

📖 Cloud Base Height

A quick field approximation for the lifted condensation level (LCL) is H (m) ≈ 125 × (T − Td), where T and Td are surface temperature and dew point in °C.

💡 Tips & Information

  • Result represents the LCL under well-mixed daytime boundary layers.
  • Use local soundings for more accurate cloud base forecasts.
  • If dew point nearly equals temperature, expect very low cloud bases or fog.
