The fine tungsten wire (10 um diameter) temperature sensor, whose response time is 5/1000sec on surface and 40/1000sec at around 30km altitude, were employed to detect turbulence intensities. For the temperture data at the sampling frequency of 16Hz were used for the tuebulence detection. The comtamination of the wake of the ballon should be carefully removed from the original data before the analysis of turbulence.
We are developing the new method to extract temperature purtarvation by turbulence at the vertical wavelength shorter than the effects of pendular movement of radiosondes.
The preliminary results show very promissing to detect turbulence intensities to compare with echo intensity of atmosphere radar.
The detailed scheme and first results are discussed in the presentation.
