• The warm interstellar gas is investigated with Gaussian components of HI profiles. The column density of the warm gas is well represented, at least at positive latitudes, by a plane parallel gas layer and, in this sense, the warm gas is pervasive also in the immediate vicinity of the sun (while the cool diffuse clouds are very few in the local hot bubble detected by soft X-ray measurements). In order compromise this fact with the recent interstellar theories which suggest the ubiquitous nature of the hot coronal gas, a hypothesis is proposed that the warm gas is composed of clouds with large internal motion. It gives an interstellar picture similar to the model given by McKee and Ostriker.HI 21-cm emissionWarm cloudsCoronal gasThe local hot bubble
