Meteorology more needd

understand a synoptic chart:

tight isobars: windy.

lows and hgihs?

isobars: areas of the same barometric pressure. shows direction and strength of the wind.

including high and low pressure.

moving from high to low along a gradient, if isobars are closer together,.

nh: face the wind low pressure is on the right. so low pressure on right, you re therefore facing the wind.

A few things to remember are that warm air follows a warm front and cold air follows a cold front. We also tend to see increased amounts of cloud and rainfall along the front itself.

x
Cold fronts tend to move faster than warm fronts and over time they can catch up with each other and create an 'occluded' front. This is shown as a purple line with a purple semi-circle and triangle next to each other. The air trapped between a warm and cold front is called a 'warm sector' and we often see low cloud and patchy light rain associated with this type of air.

“Where the isobars are closest together, the wind will be the strongest (usually near a cold front or low pressure system) and where the lines are farthest apart, the wind will be lightest (near a high pressure system),”

where could you get weather information on board:

where could you print out a synoptic chart other than the internet.

radiofax: Radiofax, also known as weatherfax (portmanteau word from the words "weather facsimile") and HF fax (due to its common use on shortwave radio), is an analogue mode for transmitting monochrome images. It was the predecessor to slow-scan television (SSTV). Prior to the advent of the commercial telephone line "fax" machine, it was known, more traditionally, by the term "radiofacsimile".
