The impact of urban fabric on the detailed climate difference in the city of Ramadi for the year 2020-2021
The microclimate patterns of the urban fabric in the city of Ramadi have varied according to its morphological stages, as it is characterized by its harsh hot and dry climate due to its location within the dry semi-desert areas. Creating a comfortable local climate through the design of organic cities, so the emergence of ancient cities with a compact mass fabric came in response to the hot, dry climatic conditions in summer.
While contemporary came with weaving stage networking scheme which was characterized by openness towards Western designs, which exacerbated the negative impact of the harsh climate in the city.
The research aims to clarify the urban planning stages of the city of Ramadi and reveal the planning reality of the organic housing stores with a compact fabric represented by the neighborhood (Al-Aziziyah and Al-Qattaneh) and the network shops with the planned fabric represented by the neighborhood (Andalusia, Al-Muoalemeen , A-Dubaat, Al-Malaeb, Al-Taamim and 5 kilos) and its impact on the formation of a micro-local climate that varies between its stores Organic housing compared to planned.
The study used local climatic observations to measure the temperature, relative humidity, and wind speed during the day and night for the summer, winter and year 2020-2021 in order to know the positive impact of the organic locality from creating a comfortable micro-climate, and the negative impact of the planned stores on its local climate, which is characterized by the formation of an uncomfortable microclimate.
The study reached the most important results, as the organic locality with a compact mass fabric recorded a decrease in the maximum temperature of the planned sites with mesh fabric at a rate of (4.0) m in summer, with an increase in relative humidity by about (2.7 %) with a lower wind speed of about (0.5 m) Second, during the winter, the organic stores recorded a limited increase in temperatures compared to the planned stores by about (3.5) m compared to the planned neighborhoods with a limited decrease in relative humidity while it reached about (3.7%), and with a lower wind speed also by (5, 0) m/s, for the planned neighborhoods, which allowed the organic locality to maintain relative humidity more than the planned neighborhood, which is characterized by a higher wind speed, which in turn transfers moisture to other neighboring areas, and this is what made the organic locality characterized by a detailed climate more comfortable than the planned network shops Thus, it will lead to the achievement of the climate efficiency of the organic stores.
As the study reached the adoption of appropriate planning indicators for the city’s climate when expanding in the future, whether when directing its streets and establishing a housing unit in a north-northeast manner towards south-southwest at an angle (30) from the geographical north line.
