  1. Key for Table 2: Number of measurements of WD.
  2. Intermediate- measurements of WD in the sector of unstable WD (under undisturbed weather conditions).
  3. NTOT - total number of measurements during DW and DB.
  4. NDES: NTOT - Ratio of WD measurements in the sector of 10-2000 to NTOT in %.
  5. NINT: NTOT- Ratio of WD measurements in intermediate sector to NTOT in %.
