Natural convection fields right above a heated horizontal circular cylinder have been examined mainly by a hot-wire anemometer calibrated for the thermal effect in a rather low air flow range, using a two-dimensional (temperature-velocity) spline function. As a result the following facts have been revealed: (1) The interpolation by a two-dimensional spline function is applicable for the calibration of a hot-wire anemometer in a rather low velocity region. (2) There is a somewhat undeveloped convection region in the natural convection field right above a heated horizontal circular cylinder. These facts are ascertained by means of a laser-doppler velocimeter and by a flow visualization method using a smoke-wire. Moreover, they are ascertained by a numerical calculation of the natural convection field, too.
