Making use of existing microclimates and introducing new ones within existing local regions can have real benefits. These differences may be slight or substantial depending on a wide range of factors such as the aspect of a given region. An undulating landscape can also produce microclimatic variety through the air motions produced by differences in density. It is clear that microclimates appear in various regions throughout the world. Microclimates are spaces in a landscape where the climate conditions significantly differ from their immediate surroundings. 4.

Microclimates are pockets of air and soil that are colder or warmer, or more or less humid, than the general climate due to the influence of slopes, walls and pavement. They also compared the temperatures of sunlit and shaded ground coverings and quantified the canopy cover of trees within its grounds. A source of a drop in temperature and/or humidity can be attributed to different sources or influences. The great variety in climates is mainly due to the geographical diversity.

Watering your plants is a manipulation of their microclimate. …modifying the local environment (microclimate) to minimize weather stresses on plants and animals. An urban microclimate is a small area of urbanized land that has different atmospheric conditions than the surrounding area. Microclimates exist, for example, near bodies of water which may cool the local atmosphere, or in heavy urban areas where brick, concrete, and asphalt absorb the sun's energy, heat up, and re-radiate that heat to the ambient air: the resulting urban heat island is a kind of microclimate.[1]. For example, in market farming (using a small amount of space intensely), plants are spaced with precision so that they quickly reach a point where the leaves touch, creating a canopy and shading the soil underneath, mitigating potential weed growth and protecting the soil. Two main parameters to define a microclimate within a certain area are temperature and humidity. On the other hand, if soil has many air pockets, then the heat could be trapped underneath the topsoil, resulting in the increased possibility of frost at ground level.[4]. c Bay Curious is a podcast that answers your questions about the Bay Area. In addition, vegetation can insulate the soil below and reduce temperature variability. Corrections? Woodlands: trees give shelter which reduces wind speed, and create shade making temperatures at ground level cooler. Creating, or being aware of having, a variety of microclimates, means you can have a wide variety of niches for more diverse planting, keeping animals, and thus increasing yields. As the air proceeds down the leeward side of the mountain, it is compressed and heated, thus promoting drier, hotter conditions there.

An area as small as a yard or park can have several different microclimates depending on how much sunlight, shade, or exposure to the wind there is at a particular spot. A soil that has a large proportion of clay retains more moisture than one that is predominantly sand. The area in a developed industrial park may vary greatly from a wooded park nearby, as natural flora in parks absorb light and heat in leaves that a building roof or parking lot just radiates back into the air. The dimensions of any particular microclimate are highly dependent on the mobility and dispersal capabilities of the organism in question.

The weather variables in a microclimate, such as temperature, rainfall, wind or humidity, may be subtly different from the conditions prevailing over the area as a whole and from those that might be reasonably expected under certain types of pressure or cloud cover. The sun is the most powerful source of energy on our planet. Albedo. As similar as lava tubes can be to caves which are not formed due to volcanic activity the microclimate within the former is different due to dominant presence of basalt.
