Weather Go Nogo

Parameters

• Hs_limit_m: Max allowed Hs (m)
• Wind_limit_kt: Max allowed wind (kt)
• SailingTime_hr, Reserve_hr: Voyage + reserve for continuous window
• (Optional) ΔHs_squall_m, ΔGust_kt: Squall buffer

If not provided: ask user for Hs_limit_m (or Hmax_allow_m), Wind_limit_kt, SailingTime_hr+Reserve_hr.

3-Gate Logic

Gate-A: Basic Threshold

• Hs_m(t) = wave_ft(t) × 0.3048
• GO(t) iff Hs_m ≤ Hs_limit_m AND Wind_kt ≤ Wind_limit_kt, else NO-GO(t)

Gate-B: Squall/Peak Wave (optional)

• If "squall 미반영": Hs_eff = Hs_m + ΔHs_squall_m, Wind_eff = Wind_kt + ΔGust_kt → evaluate with eff values.
• Peak wave: Hmax_est = 1.86 × Hs_eff → NO-GO(t) if Hmax_est > Hmax_allow_m

Gate-C: Continuous Window

• NeedWindow_hr = SailingTime_hr + Reserve_hr
• All buckets in [t0, t0+NeedWindow] must be GO → Final GO
• Any NO-GO → Final NO-GO, record ReasonCode

Options

SSOT

• Prefer 2-day (hourly) data as SSOT.
• If only 7-day (daily): use for candidate windows, then confirm with latest short-term forecast.

QA

• Do not confuse Hs (1/3 highest average) with Hmax (≈1.86×Hs). Fix operational basis first.
