Analysis of Wind Speed, Humidity and Temperature: Variability and Trend in 2017

Abstract In recent years, it has been observed that numerous cases of windstorm event. There are many factors that cause windstorms to occur. The factors of meteorology, urban morphology, the topography need to be studied to find out the cause of windstorms. The work analyzed meteorology factors such as: wind speed, humidity and temperature, occurring in 2017. Meteorological data from the Department of Environment Malaysia (DOE) station, allow determining the wind speed, humidity and temperature data daily in 2017. As well as, the pattern of parameter and their relationship between them being determined. The pattern of wind speed monthly was inconsistent. The highest average wind speed in 2017 was 4.72 m/s and the lowest average was 0.56 m/s. While humidity, the highest average was 83.12 % and the lowest average humidity was 72.33 %. For temperature, the maximum average for 2017 was 28.43 °C and the minimum average was 26.26 °C. The correlation of wind speed between humidity and temperature was -0.256 and 0.278, which is low correlate. That must be other active factors that influence the wind speed and contribute to the windstorm event. Wind speed, humidity and temperature during the windstorm event on 11 February 2017 was analyzed. During the windstorm event, the wind speed blows up to 15.7 m/s while the humidity reading decrease to 68.4 % and the temperature was 30.9 °C. When the wind speed reading is high, the temperature reading also increases and the humidity reading will go down and vice versa and has caused the windstorm event to happen.
