The predictability of mean temperature is investigated for ten stations located, separately, in all climatic regions of the country in terms of information transmission as the measure of climatic predictability. Evidence suggests that the transmission at a range of scales (pentad, decade, month and year) displays attenuation features of their own in relation to the climatic background. As such, the temperature information transmission represents better the predictability. The consistent attenuation in the measured and model-yielded temperature information allows to use the transmission as a useful means for testing the predictability dealt with by a model.
