  • 2001:

16 19 sondes per day

  • 2001: 16-19 sondes per day
  • 2002: 22-24 sondes per day
  • BUT: main problem is absence of regularity:
  • 1999: only 2 stations provided daily regular data

Conclusions

  • Existed RAOB and SYNOP networks in

Siberia is not uniformly distributed there Siberia is not uniformly distributed – there are several gaps in informatively important d i domains: Chukotka, Arctic coast, East Siberia (high latitudes)

  • There is urgent necessity in additional

e e s u ge t ecess ty add t o a

  • bservations, especially in North-Eastern

part of Siberia. part of Siberia.
