Dear Tom, What are “packed isobars”? Thanks, Melissa Dear Melissa, Hourly weather observations that include sea-level pressure are plotted or printed on weather maps. Isobars are drawn by ...

Isobars are lines/areas of equal pressure represented on a weather map. When isobars become very tightly grouped together it indicates a "tight pressure gradient" (steep slope).

On the weather forecasts, you often show plots of isobars moving and then seem to indicate that the winds will be running parallel to the ... troughs and frontal systems we show on our maps, ...

THEY pop up on our TV screens every single day but more often than not we have no idea what we’re actually looking at.

Isobars are lines on a weather map joining together places of equal atmospheric pressure. On the map the isobar marked 1004 represents an area of high pressure, while the isobar marked 976 ...

On a weather map an East Coast Low is denoted much the same way as a low pressure system. Its hit 23.5°C at Mallacoota, the highest July temp on record! This is due to a Foehn Wind https://t.co ...

On the weather forecasts, you often show plots of isobars moving and then seem to indicate that the winds will be running parallel to the isobars. We all know that winds should be perpendicular to ...
