An isohyet is a type of map contour line that displays precipitation.
A contour line, also known as an isarithm, isoline, or isopleth, is a contour line on a map that represents an imaginary line on the land’s surface.
A line of contours is frequently a function of two variables and is defined as a curve connecting points where the function’s value is the same.
An isohyet, also known as an isohyetal line, is a line on a map that connects points that have the same amount of precipitation at the same time or during a specific storm.
An isohyetal technique is used to estimate average rainfall in a specific region.
On a diagram, the technique is used to draw similarly precipitous lines.
Furthermore, an isohyetal technique uses topographic data in conjunction with other data to generate accurate estimates.
Rainfall values can be plotted on a proper basemap at their respective stations using this method.
Isohyets are then drawn to generate an isohyetal map.
Interpolation between rain gauge stations serves as the primary foundation for Isohyetal lines.
When constructing isohyets, it is assumed that precipitation varies linearly between two different stations unless there is a sudden or brief change in topography indicating otherwise.
Final Answer:
Isohyets are imaginary lines created on a map that link places with equal rainfall.
These are often depicted on a weather map.
