East Coast Low. An intense low pressure systems that often develop very rapidly (sometimes explosively) in the Tasman Sea close to (within 5° usually) the east coast of Australia. It often brings gale-force or storm-force winds, phenomenal seas and localised heavy rainfall, and may persist for a few days. ECL's are responsible for many of the extreme rainfall maxima along the NSW coastline. ECL's are generally "cut off" from the usual westerly airflow.

Electronic Cash Letter, electronic files containing pertinent information from check MICR lines that are used to present the corresponding checks electronically for payment.

Erosion Control Line. A line established in connection with beach nourishment projects by the State of Florida Governor and Cabinet. It defines the line of delineation between the state and upland ownership of the beach. Private or public property may extend landward of the line while the state has jurisdiction seaward of the line. The line is based on a detailed survey of the location of the mean high water line. The ECL must be established prior to the beach nourishment project construction. The ECL should not be confused with the CCCL (see above).

Abbreviation for mitter- oupled ogic.
