Abstract

This study aims to analyse temperature changes in NTT Province over the past 50 years, by comparing two periods, namely period I (1971-2000) and period II (1991-2020). Statistical analysis methods were used to examine temperature differences between the two periods, calculate the percentage of temperature change, and present time series graphs of average monthly temperatures. In addition, spatial analysis was conducted to investigate the seasonal temperature changes of December, January, February (DJF); March, April, May (MAM); June, July, August (JJA); and September, October, November (SON) regionally in NTT Province. Temperature data for 50 years was obtained from the European Centre for Medium-Range Weather Forecasts (ECMWF) reanalysis data, providing a strong basis for understanding the dynamics of temperature change with a high degree of accuracy. The results of this study show a steady increase in temperature in the 1991-2020 period by 0.894% compared to the 1971-2000 period, with a positive linear regression (0.0407), while the 1971-2000 period shows a less significant increase (0.0188). Spatial analysis shows a seasonal average temperature increase of 0.957°C in the 1991-2020 period. The findings on climate change characterised by temperature changes are expected to be the basis for more effective adaptation and mitigation policies in the face of climate change at the local level. This research is an important step in understanding the dynamics of climate change in vulnerable areas such as NTT Province.

Abstract

This study aims to analyse the trend of rainfall changes in Yogyakarta Special Region (DIY) Province during the period 1970-2019 based on ERA5 reanalysis data. The analysis method of this study involves the use of 50 years of ERA5 rainfall data with high spatial and temporal resolution. The data was processed using the Climate Data Operator (CDO) to obtain monthly average values in five specified periods. In Period I to II, there was an increase in rainfall of +8%, especially in 5 months ranging from 18% to 37%, while the other 7 months showed a downward trend. In Period II to III, rainfall decreased by -7%, mainly in 7 months ranging from 3% to 32%, while the other 5 months showed an increase. In Period III to IV, there was an even greater decrease in rainfall, reaching -8%, accompanied by a decrease in 9 months ranging from 2% to 58%, while the other 3 months showed an increase. In Period IV to V, there was again a significant increase of +12%, mainly during 10 months ranging from 2% to 97%, while the other 2 months showed a decrease. The increase in rainfall mainly occurs in certain time intervals, while the peak of rainfall tends to shift, indicating that climate change has occurred in Yogyakarta.

Abstract

Weather data is an essential record of various weather elements that serve as the basis for forecasting future weather and climate conditions. Managing large volumes of data requires appropriate methods and applications to process the data to produce accurate results. The data used is reanalysis data taken from Copernicus and its verifiers from observational data. Data processing using CDO tools. The results of this study show the RMSE value between the observation data and the model of 1.24, where the model data tends to be smaller than the observation data. Next, there was an increase in monthly average temperature during the period 1970 - 2019. A significant increase in temperature was seen from the period 1970 - 2019 the lowest average temperature was 26.09oC, 26.36oC, 26.45oC, 26.69oC and 26.96oC respectively. The monthly temperature increase reached 0.87oC during the period 1970 - 2019. This is clear evidence that climate change has occurred, characterized by significant temperature changes in the Yogyakarta region.
