Isohel is a rare word that is spelled as /ˈaɪsəʊhɛl/ in IPA phonetic transcription. The word is derived from the Greek word iso, which means equal or same, and helios, which means sun. Isohel refers to a line on a map that connects points of equal or uniform solar radiation. The spelling of the word is straightforward and phonetically accurate, with each character representing a specific sound in English. Despite its infrequent usage, isohel is an important concept in geography and meteorology.
Isohel is a term used in meteorology to describe a line on a map that connects points of equal or constant sunshine or sunlight duration. It is derived from the Greek words "iso" meaning equal and "helios" meaning sun. The concept of isohels is closely related to the study of solar radiation and climate factors.
Isohels are usually represented on weather maps to visualize the distribution of sunlight across a given area. They are depicted using a series of lines that connect regions receiving the same amount of sunlight duration during a specific time period, typically a day or a year. These lines are contour lines that show the geographical pattern or gradient of sunlight distribution.
The spacing between isohel lines on a map provides information about the intensity or rate of change in sunlight duration across the area. Areas with closely spaced isohel lines indicate a rapid change in the amount of sunshine, whereas areas with widely spaced lines indicate a more gradual change. This information can be helpful in understanding regional disparities in solar energy availability, which are relevant for various applications such as agriculture, solar power generation, and climate assessments.
Overall, isohels are an important tool in meteorology for depicting the distribution of sunlight duration across different regions, helping scientists and researchers understand and analyze variations in solar radiation and its impact on various climate phenomena.
The word "isohel" is derived from the combination of two Greek roots: "iso", meaning equal, and "helios", meaning sun.
The term "isohel" was coined in the field of meteorology to refer to lines or areas on a map that connect places with equal duration of sunshine or equal solar radiation. The word "isohel" is commonly used in climatology and solar energy studies to describe these specific geographic areas.
It's important to note that while the roots of the word provide a clear indication of its meaning, the specific combination and usage of "isohel" in the scientific context is a more recent development.
