Abstract
ALONG-FELT want of the weather forecaster has been a methodical classification of weather types associated with the various weather conditions which present themselves. The weather-chart commonly offers a picture familiar enough to the forecaster, but there is much connected with the movement and development which depends upon the bounding conditions. A low-pressure system or depression when appearing off our south-west coasts may have a clear path to the north-eastward, the high-pressure system in its front giving way to its progress. On the other hand, the high-pressure system or anticyclone may be well established and may maintain its ground, thus compelling the advancing disturbance to adapt its track to the situation—a feature of no uncommon occurrence, but one offering considerable difficulty to the work of the forecaster.
