We have thus far been studying isobaric charts based on barometer readings made at a single moment of time.
Pressure Gradients on Isobaric Charts of the Globe.
Lines of pressure-decrease should be drawn on allisobaric charts studied in the class, as they are highly instructive.
Color brown all parts of your six isobaric charts over which the pressures are below 29.
The mean annual and mean monthly isobaric charts of the world show the presence of great oval areas of low and high pressure covering a whole continent, or a whole ocean, and keeping about the same position for months at a time.
The isobaric charts of the globe for January and July show that the pressure gradients are stronger (i.
Thus, on the isobaric chart showing the mean pressure over the world in January, there are seen immense areas of high pressure (anticyclones) over the two great continental masses of the Northern Hemisphere.
Study the isobaric chart of each day of the series by itself at first.
What relations do you discover between temperature distribution and pressure distribution on the isothermal and the isobaric charts for the same day?
Examine the rates of pressure decrease upon the series of isobaric charts.
If we examine isobaric charts for January and July, we shall find that these gradients are stronger or steeper over the Northern Hemisphere in the former month than in the latter.
Examine the series of isobaric charts to see how the lines of pressure decrease run.
Draw lines of pressure decrease for the sixisobaric charts, as you have already done on the isothermal charts.
It is to be noted that isobaric lines are the intersections of inclined isobaric surfaces with the surface of the earth.
The isobaric charts published in the report of the Nansen expedition show that the North Atlantic low-pressure area is more or less well developed in all months.
The rapid southward decrease of pressure, which is so marked a feature of the higher latitudes of the southern hemisphere on the isobaric charts of the world, does not continue all the way to the South Pole.
The isobaric and wind charts show that on the whole the winds blow out from the inner polar basin, especially in winter and spring.
Defn: Denoting equal pressure; as, an isobaric line; specifically, of or pertaining to isobars.
Also, the theory, method, or application of isobaric science.
It ought to be said, perhaps, that this result does not depend upon my judgment to any appreciable extent, but was legitimately worked out from the observations and isobaric lines.
The above list will hopefully give you a few useful examples demonstrating the appropriate usage of "isobaric" in a variety of sentences. We hope that you will now be able to make sentences using this word. Other words: atomic; cyclic; cyclical; cyclonic; elemental; isometric; subatomic
