Weather front areas of precipitation help determine the frontal type and location. There are two different meanings used within meteorology to describe weather around a frontal zone. The term "anafront" describes boundaries which show instability, meaning air rises rapidly along and over the boundary to cause significant weather changes. A "katafront" is weaker, bringing smaller changes in temperature and moisture, as well as limited rainfall. A cold front is located at the leading edge of the temperature drop off, which in an isotherm analysis shows up as the leading edge of the isotherm gradient, and it normally lies within a sharp surface
Pe (letter) of words, the letter's written form changes to a "Pe/Fe Sophit" (Final Pe/Fe): . When a word in modern Hebrew borrowed from another language ends with , the non-final form is used (e.g. "Philip"), while borrowings ending in still use the Pe Sofit (e.g. "fun", from Arabic).
