Climate Indice in Central Java

1. Climate Indice in Central Java By AgusSudaryatno Citeko, 2 April 2012

2. The Stations in Central Java 39 Station Agriculture Meteorological Station Central Java have 39 Agriculture and 6 BMKG’s Stations, but from all of them we only 4 stations that have good data series. They are Borobudur Agriculture Meteorologi Station, Cilacap Meteorological Station, Tegal Meteorological Station and Semarang Climatological Station 6 BMKG’s stations in Central Java 4 stations that have good data series

3. 3 Stations have daily dataset From 4 stations that have good data series, only 3 stations that have daily dataset. The station are Cilacap Meteorological Station, Semarang Climatological Station and Tegal Meteorological Station. The Borobudur Agriculture Station only have monthly dataset.

4. The processing Climate indice • To Obtain te Cilmate Indice, we do : • Collecting Dataset • Check the Quality Control • Check the homogeneity • Calculation Indice and trend

5. The processing Climate indice (Continued) • Data Quality Control : • The data must have some criteria : • Precipitation >= 0 mm • TMax > TMin

6. Chek the data homogeneity Data Homogeneity of Precipitation in Borobudur Station:

7. Chek the data homogeneity (continued) Data Homogeneity of Precipitation in Cilacap Station:

8. Chek the data homogeneity (continued) Data Homogeneity of Precipitation in Semarang Station:

9. Chek the data homogeneity (continued) Data Homogeneity of Precipitation in Tegal Station:

10. Chek the data homogeneity (continued) Data Homogeneity of TMax in Borobudur Station:

11. Chek the data homogeneity (continued) Data Homogeneity of TMax in Cilacap Station:

12. Chek the data homogeneity (continued) Data Homogeneity of TMax in Semarang Station:

13. Chek the data homogeneity (continued) Data Homogeneity of TMax in Tegal Station:

14. Chek the data homogeneity (continued) Data Homogeneity of TMin in Borobudur Station:

15. Chek the data homogeneity (continued) Data Homogeneity of TMin in Cilacap Station:

16. Chek the data homogeneity (continued) Data Homogeneity of TMin in Semarang Station:

17. Chek the data homogeneity (continued) Data Homogeneity of TMin in Tegal Station:

18. The processing Climate indice (Continued) Precipitation Total in Borobudur Station:

19. The processing Climate indice (Continued) Precipitation Total in Cilacap Station:

20. The processing Climate indice (Continued) Precipitation Total in Semarang Station:

21. The processing Climate indice (Continued) Precipitation Total in Tegal Station:

22. The processing Climate indice (Continued) Tmax mean in Borobudur Station:

23. The processing Climate indice (Continued) Tmax mean in Cilacap Station:

24. The processing Climate indice (Continued) Tmax mean in Semarang Station:

25. The processing Climate indice (Continued) Tmax mean in Tegal Station:

26. The processing Climate indice (Continued) TMin mean in Borobudur Station:

27. The processing Climate indice (Continued) TMin mean in Cilacap Station:

28. The processing Climate indice (Continued) TMin mean in Semarang Station:

29. The processing Climate indice (Continued) TMin mean in Tegal Station:

30. The processing Climate indice (Continued) Trend of the climate indice in Cilacap :

31. The processing Climate indice (Continued) Trend of the climate indice in Semarang :

32. The processing Climate indice (Continued) Trend of the climate indice in Tegal :

33. Summary • The homogeneity of precipitation data series for all of station are good • The homogeneity of maximum temperature for 3 station are not good • except Semarang Climatological Station is good. • The homogeneity of minimum temperature for Cilacap and • Tegal Meteorological Station are good but for Borobudur Agriculture • Meteorological Station and Semarang Climatological Station are not • good. • Trend of precipitation for all of station are decrease, but • Trend of maximum and minimum temperature for all station are • increase.
