Widely spaced isotherms (line A-B in Figure 5.12) indicate a small change in temperature over distance and closely . First, we must identify the two contours that lie on either side of "P." In some cases the contours that we need are clearly labeled; however, in other instances, you will need to use the contour interval (1,000 feet, in this case) to "count" up or down from a labeled contour. Which type of forecast is impacted the most by the butterfly effect? Meteorologists use isobars on weather maps to depict atmospheric pressure changes over an area and to make predictions concerning wind flow. Log in for more information. Answer: Point "P" is located inside the 45 degree Fahrenheit isotherm. If isotherms are approaching your point of interest that are colder than the temperature at your point of interest, then it is cold air advection. We know that point "P" is not equal to either of these values because it does not lie on one of the contour lines. (Choose 4) Meanwhile, regions of low pressure are often somewhat unsettled (cloudy with precipitation). The lines are drawn using data from mean sea-level pressure reports. Search for an answer or ask Weegy. (c) Do you think that the energy carried off by the neutrinos is deposited in the star? Use Weather Maps to Make a Forecast A Lesson Plan.
