Fronts move with the wind so with our prevailing westerlies they usually travel from west to east with cold fronts moving faster than warm fronts. The way these are plotted varies depending on whether the station is an automatic or manned observing site. The projection might seem a little bit odd, but having north, where the lines of longitude converge, in the top left corner means we can see as much as possible of the relevant area around the UK. When different parameters of the earth's atmosphere are viewed together at the synoptic scale then large-scale weather patterns emerge, such as extratropical cyclones and their associated fronts.
