Temperature determined by averaging the 24 hourly readings or by adding the maximum and minimum temperatures for a hour period and dividing by 2. Daily Temperature Range. The difference in a day's maximum and minimum temperatures.

Monthly Mean Temperature. Calculated by adding together the daily means for each day of the month and dividing by the number of days in the month. Annual Mean Temperature. An average of the 12 monthly means. Annual Temperature Range. Computed by finding the difference between the warmest and codes mean temperatures. Temperature Gradient. The amount of temperature change per unit of distance. Closely spaced isotherms indicate a rapid rate of temperature change, whereas more widely spaced lines indicate a more gradual rate of change.

Controls of Temperature. Factors that cause temperatures to vary from place to place and from time to time. What are the controls of temperature? Variations in sun angle and length of daylight which depend on latitude - differences in the receipt of solar radiation. Differential heating of land and water. Ocean currents. Geographic position. Cloud cover and albedo. Why do isotherms never cross?

An isotherm should never split, cross, or touch another isotherm, because then at the crossing point it would have two different temperature values, which is physically impossible. What are isotherms and what is their purpose? What are isotherms and why do meteorologists use them or what is their purpose?

An isotherm is a line of connecting points of equal temperatures. They are used to observe the distribution of air temperatures over a vast area. Why should isotherms be smoothly drawing curves? Isobars show pressure changes over space and help to describe large scale weather patterns over a region.

With isotherms, isobars make it easier to read and analyze weather maps. Looking at patterns of temperature and pressure can help determine weather conditions a few days ahead.

Which month is most likely to be the hottest in the northern hemisphere? What are isotherms in chemistry?

Each curve is called an isotherm. What is isotherm map? Definition of isotherm. How can you tell if the temperatures inside the isotherm circle are higher or lower than the isotherm value?

Isotherms is the name given to the lines on the map. Isotherms are drawn in ten-degree intervals. Always label the isotherm value. Thus they shift north and south much more over land through the year than they do over water. Comparing the difference in the values of the isotherms between seasons, the smallest temperature ranges are found near the equator while the largest are found over high latitude continental interiors, Siberia for example.

The difference in temperature across latitudes is the latitudinal temperature gradient. The winter hemisphere January for the Northern hemisphere, July for the Southern Hemisphere has the larger temperature gradients as shown by the closely spaced isotherms.

Also note that the temperature gradient is steepest in the midlatitude to subarctic geographical zones. Here is where strongly contrasting tropical and polar type air masses clash along the polar front. Previous Continue.
