Climate Indice in Central Java
description
Transcript of Climate Indice in Central Java
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
39 Station Agriculture Meteorological Station
6 BMKG’s stations in Central Java
4 stations that have good data series
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.
To Obtain te Cilmate Indice, we do :
Collecting Dataset Check the Quality Control Check the homogeneity Calculation Indice and trend
Data Quality Control :
The data must have some criteria :• Precipitation >= 0 mm• TMax > TMin

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.
