coldspot

A cold spot is a colloquial term used to describe an area that is noticeably colder than its surroundings. This phenomenon can occur in various contexts, from the natural environment to manufactured spaces.

In meteorology, a cold spot can refer to a localized region of lower atmospheric temperature, often associated with specific weather patterns or topographical features. These can manifest as areas experiencing frost when other regions do not, or as pockets of cooler air within a larger air mass.

Within buildings, cold spots are commonly experienced as drafts or areas where heat does not seem to distribute effectively. These can be caused by poor insulation, air leaks around windows and doors, or inefficient HVAC system design. Identifying and addressing these cold spots is often a goal in home energy audits to improve comfort and reduce heating costs.

The term "cold spot" is also sometimes used in paranormal investigations, referring to an unexplained localized drop in temperature believed by some to be evidence of spectral activity. However, these occurrences are not scientifically recognized and are generally attributed to environmental factors or psychological perception. The consistent, measurable nature of cold spots in physical environments distinguishes them from anecdotal paranormal claims.
