Experiments with a single circular fire source were carried out in an unconfined space to understand temperature property of the fire plume in the presence of cross-wind. Three-dimensional measurement of temperature field created by the inclined fire plume was conducted and radiative heat fluxes at ground level along the centerline of the fire source whose direction is in parallel to the cross-wind were also measured. Followings become clear from a comparison between measured data and plume properties without cross-wind. Firstly, temperature along the inclined fire plume axis (?To) decreased rapidly. Secondly, plume radius based on temperature whose direction is in perpendicular to the inclined fire plume axis was larger. Furthermore, a relation between temperature in the vicinity of ground along the centerline of fire source whose direction is in parallel to the cross-wind (?Tg_o) and ?To can be expected to hold regardless of the distance from the center of fire source and heat release rates.
