Unlike cold core lows, these lows produce much of their cloud cover and precipitation during the nighttime. Tropical cyclones exhibit this temperature pattern. Warm Core Low A low pressure area which is warmer at its center than at its periphery.

Although the two terms are not properly interchangeable, both imply the presence of lifting in low levels. Low-level warm advection sometimes is referred to (erroneously) as overrunning. Warm Advection Transport of warm air into an area by horizontal winds.

"Wall cloud" also is used occasionally in tropical meteorology to describe the inner cloud wall surrounding the eye of a tropical cyclone, but the proper term for this feature is eyewall. Wall clouds should be monitored visually for signs of persistent, sustained rotation and/or rapid vertical motion. Rotating wall clouds usually develop before strong or violent tornadoes, by anywhere from a few minutes up to nearly an hour. When seen from within several miles, many wall clouds exhibit rapid upward motion and cyclonic rotation. Wall clouds can range from a fraction of a mile up to nearly five miles in diameter, and normally are found on the south or southwest (inflow) side of the thunderstorm. Wall Cloud A localized, persistent, often abrupt lowering from a rain-free base.
