Utilization of WRF-Chem Modelling for Barujari Mount of Volcanic Ash Distribution Analysis

---

By the development of NWP (Numerical Weather Prediction), the using of weather model is used to being done and it get better and better. Starting from a Rick Anthes’ 3layer hurricane model on 1960, a mesoscale model on 1970s, MM4 on 1980s and MM5 model on 1990s which was developed until the third version. Then WRF (Weather Research and Forecasting) launched in beta version up to now WRF was launched with different core in ARW and NMM with additional modules which is also included in WRF-Chem and WRF-Fire. WRF-Chem is a WRF Mode that has chemistry additional module which is able to simulate air quality on regional scale, on field analysis and interaction analysis between clouds and chemical particles in atmosphere. The eruption of Barujari Mount in Lombok island on 4th of November 2015 caused 3 airports was closed, they are International Airport of Lombok, Ngurah Rai Airport and Banyuwangi Airport. The height of Barujari Mount is about 2376 ms above sea level. The height of Barujari mount’s eruption reached about 20,000 feets. To analyse volcanic ash spread using WRF-Chem model, we can use NCEP FNL on 3rd of November 2015 on 00.00 UTC until 5th of November 2015 on 00.00 UTC. NCEP FNL is a product from GDAs which is a global data asimilation system that is frequently collectingdata from GTS. Volcanic ash spreading data from Himawari-8 is used as a comparison. From the analysis model using WRFChem, volcanic ash on 850 mb layer until 500 mb on spreading to South West until West area of Lombok island. It shows the conformity in spreading direction on Himawari-8 images. Even though, there are several differences with Himawari-8 where spreading direction on WRF-Chem went to West-North West and Himawari-8 satellite images showed the spreading volcanic ash moved to South West-West of Lombok island.
