Abstract

The water, a built environment, and a palm grove are an impressive trilogy making up the formidable oasis, rendering it strong enough to survive the harsh desert climate. Furthermore, the interaction between them creates several natural and physical phenomena. This research discusses the oasis effect, one of the most significant phenomena in the oasis ecosystem; this effect has been treated as a cooling phenomenon in theories and mathematical models. Therefore, we aimed to examine the impact and limits of this phenomenon in regard to the microclimate of oases through digital simulation, using the SPUCAL_oec software (Simulation Platform of Urban Climate in Arid Lands _ Oases Effect Calculator). Based on an innovative mathematical model, we developed SPUCAL_oec as an innovative vision for this green phenomenon, programmed to predict, calculate, and simulate the behavior and limits of the palm grove on the oasis microclimate. Finally, the results of SPUCAL_oec model showed that the oasis effect impacted the oasis microclimate owing to the existence of the palm grove. This effect could be as large as 6°C of temperature decrease and 12% increase in relative humidity. Furthermore, the SPUCAL software can aid designers and planners in making decisions regarding their design process.

预测绿洲效应作为热沙漠中一种冷却现象的极限

水、建筑环境和棕榈树林组成了令人印象深刻的三部曲，构成了令人敬畏的绿洲，使它足够强大，能够在恶劣的沙漠气候中生存。此外，它们之间的相互作用创造了一些自然和物理现象。绿洲效应是绿洲生态系统中最重要的现象之一。在理论和数学模型中，这种效应被视为一种冷却现象。因此，我们旨在利用SPUCAL_oec软件(干旱地区城市气候模拟平台_绿洲效应计算器)，通过数字模拟来研究这一现象对绿洲小气候的影响和局限性。基于创新的数学模型，我们开发了SPUCAL_oec，作为对这一绿色现象的创新愿景，通过编程来预测、计算和模拟绿洲小气候下棕榈林的行为和限制。SPUCAL_oec模型结果表明，绿洲效应对绿洲小气候的影响是由于棕榈林的存在。这种影响可能高达6°C的温度下降和12%的相对湿度增加。此外，SPUCAL软件可以帮助设计师和规划人员在设计过程中做出决策。
