Wind ROS Wind Load and Climate Analysis of Adama Wereda Oromia Ethiopia

Climate change induced irregularities in amount and frequency of extreme temperature and precipitation events are likely to increase across the globe. Climate change has created a new challenge to hamper development process throughout the world. For this analysis meteorological daily rainfall station data in millimetre, maximum temperature and minimum temperature data in degreecentgrade, wind speed in meter per second and direction in degree data including historical period from 2025-1995 G. c was taken form Ethiopian Meteorology Institute for a study area of Adama wereda. Result indictes Climatological rainfall (long-term monthly average) in Adama wereda has raised pic in the month of July and August with amount of above 200 mm (two hundred mm). The average daily temperature reaches from 18°C to 24°C prevailed in Adama wereda of Oromia region Ethiopia. Extreme maximum temperature of Adama wereda was recorded 36.1°C and Extreme minimum temperature of Adama wereda was recorded 3.1°C. Wind Rose diagrams has displays for Adama wereda average wind speed for winter season mostly dominated from 4m/s to 7.5m/s and the wind direction in this season dominated to ENE (East North East) direction of in Adama wereda and Wind Rose diagrams has displays for Adama wereda average wind speed for Summer season mostly dominated from 3m/s to 7m/s and the wind direction in this season dominated to WSW (West South West) and SSW (south south west) direction of in Adama wereda. The wind load analaysis indicates for windward wall is 0.0112 km/m 2 and for leeward is - 0.0048km/m 2 . This analysis of climate pattern and trends will have benefits for decision makers and strategy in the study area.
