subroutine	znot_m_v6 (uref, znotm)
	add fitted z0,zt curves for hurricane application (used in HWRF/HMON) Weiguo Wang, 2019-0425
subroutine	znot_t_v6 (uref, znott)
	Calculate scalar roughness over water with input 10-m wind For low-to-moderate winds, try to match the Ck-U10 relationship from COARE algorithm For high winds, try to retain the Ck-U10 relationship of FY2015 HWRF.
subroutine	znot_m_v7 (uref, znotm)
	Calculate areodynamical roughness over water with input 10-m wind For low-to-moderate winds, try to match the Cd-U10 relationship from COARE V3.5 (Edson et al. 2013) For high winds, try to fit available observational data Comparing to znot_t_v6, slightly decrease Cd for higher wind speed.
subroutine	znot_t_v7 (uref, znott)
	Calculate scalar roughness over water with input 10-m wind For low-to-moderate winds, try to match the Ck-U10 relationship from COARE algorithm For high winds, try to retain the Ck-U10 relationship of FY2015 HWRF To be compatible with the slightly decreased Cd for higher wind speed.
