Abstract

In This work estimation have been done to measure Obkhove Length and sensible heat flux in BAB AL - MUADHAM BAGHDAD city ,as well , we found an exponential relation between Obkhove Length and sensible heat flux and that lead to practical equation can be used under specific condition .The observations have been made for wind speed and temprature at two levels 20 m ,15 m by used aslow respounse instrument and in aselected hours of the day from 16:00 LT to 20:00 LT. The time rang of observation lengthed throughout amonth (April 2006). The maximam Obkhove Length valu was (- 249.2) and manimum Obkhove Length valu was (- 2638.1m ) , as well,The maximum heat flux valu was (19.7w/m2) and the manimum heat flux valu was (1.9 w/m2).
