that is cooler than the surrounding Arid, dry area due to evaporation or evapotranspiration of a water source or plant life and higher albedo of plant life than bare ground. The oasis effect is so-named because it occurs in desert oasis, oases. urban planning, Urban planners can design a city's layout to optimize the oasis effect to combat the urban heat island effect. Since it depends on evaporation, the oasis effect differs by season.


Causes

An oasis contains moisture from a water source and/or plants. When that water evaporation, evaporates or Transpiration, transpirates, heat from the surroundings is used to convert liquid to gas in an Endothermic process, endothermic reaction, which results in cooler local temperatures. Moreover, vegetation has a higher albedo than bare ground, and reflects more sunlight, leading to lower land Temperature, temperatures, lower Atmosphere of Earth, air temperatures, and a cooler local

Seasonal Effects

The oasis effect occurs most prominently during the summer because warmer temperatures lead to more evaporation. In the winter, the oasis effect operates differently. Instead of making the oasis cooler, the oasis effect makes it warmer at night. This occurs through the fact that trees block heat from leaving the land. Basically, radiation cannot be emitted back into the Atmosphere of Earth, atmosphere because the trees intercept and absorb it.


Urban Planning

The oasis effect plays a role in Urban planning, urban development because plants and bodies of water result in cooler City, cities. Accordingly, cities with Park, parks will have lower temperatures because plants have higher albedo than bare ground or Road, roads. Areas with higher albedo Reflection (physics), reflect more light than they Absorption (electromagnetic radiation), absorb, leading to cooler temperatures. Normally, cities are hotter than their suburbs due to dense population, dark buildings and roads, and pollution; this is known as the urban heat island effect. However, by careful placement of Tree, trees, parks, and plant life, cities can create their own oasis effect. By maintaining plant life throughout a city, urban planners can produce an oasis effect to offer the urban heat island effect; even a small scattering of trees can significantly reduce local temperatures. However, concerns can arise in arid regions with limited water sources where city planners may not want to leave water sources out in the open to evaporate, and may not want to sacrifice water for upkeep of plants.


Music

The Oasis effect refers to the idea of music being deemed as substandard by the general public when in actuality the music is satisfactory, it is just overplayed.
