Hello friends, here I show you How to Make Orographic Rainfall Model with Thermocol and other basic objects. Please see carefully and make it easily. It will help the students of the school/college to create their project. Thank you.
Materials Required: Thermocol, Tissue Paper, Acrylic Colors, Cotton Cloth, White Glue, Pin, Knife, etc.
WHAT IS OROGRAPHY:
Orography is defined as the study of the topography relief of mountains, and more broadly includes hills and any part of an elevated terrain region. Orography is also called orography. Orology or orology falls within the broader discipline of geomorphology.
WHAT IS OROGRAPHIC PRECIPITATION:
Orography precipitation is defined as snow, rain, or other precipitation, which is formed when moist air is lifted as it moves over a range of mountains, As the air rises and cools, the orographic clouds form and serve as the precipitation source, where most falls upwind of mountain ridge. Also falls at a shorter distance downwind of the range are called spillover, sometimes. On the lee side of the similar mountain range, rainfall usually becomes low, and the area is in a rain shadow. Very heavy precipitation typically takes place upwind of a prominent mountain range, which is oriented across a prevailing wind from a warm ocean.
CAUSE OF OROGRAPHIC RAINFALL:
Let us know the cause of orographic rainfall briefly, as discussed below.
Two things are directly responsible for the cause of orographic rainfall throughout the world and the rainfall can be expected or forecast by the same. Those two things are given as.
• Humid atmospheric conditions, in which the clouds are approaching full saturation that would lead observers to believe that it will form measurable precipitation.
• An incline, for example, which is exactly would be found going up a mountain.
Orographic rainfall is caused exactly by these two things, but in sample terms, it means “ rainfall associated with or which is induced by the presence of mountains”. Nothing is more specific here except the description of rainfall, which is cause by “the presence of mountains”.
EXAMPLE OF OROGRAPHIC PRECIPITATION :
Examples of the precipitation, which are caused by mountains include rainfall from orographic stratus formed by forced lifting and precipitation from orographic cumuli caused by daytime heating of mountain slopes. Several classic examples of locations that have excessive annual precipitation are located on the mountain’s windward slopes facing a steady wind from a warm ocean.
USES OF OROGRAPHIC PRECIPITATION :
Let us look at the important uses of orographic precipitation, which are described below.
Elevated land masses and mountain ranges have a primary impact on the global climate. For example, the elevated areas of East Africa substantially determine the strength of the indian monsoon. Also, in scientific models, like general circulation models, orography determines the lower boundary of model over land.
When tributaries of the river or settlements by the river are listed in the ‘orographic sequence’, they are present in the order from the highest (which is nearest the mouth). This listing tributaries method is the same as the Strahler Stream Order, in which, the headwater tributaries are listed as category 1.
