Conclusions• Existed RAOB and SYNOP networks in
Siberia is not uniformly distributed thereSiberia is not uniformly distributed – there are several gaps in informatively important d idomains:Chukotka, Arctic coast, East Siberia (high latitudes)
• There is urgent necessity in additional e e s u ge t ecess ty add t o aobservations, especially in North-Eastern part of Siberia.part of Siberia.
