Winters are cold and dry in freezing climates. Winters are cool to cold with periodic snow and temperatures often below freezing. Winters can be cold with temperatures that are frequently below freezing. Jack Frost is a personification of frost, ice, snow, sleet, winter, and freezing cold. It rarely gets sleet or freezing rain. Hepatocytes are intensely sensitive to damage during the cycles of cryopreservation including freezing and thawing. They should not be used in climates with temperatures below freezing. Bacteria survives but does not grow in freezing temperatures. Ice wedges enlarge with successive seasons of freezing and thawing. They are a poor approach to air-entrainment which improves resistance to freezing under low temperatures. They are resistant to ultraviolet radiation, desiccation, high temperature, extreme freezing and chemical disinfectants. Freezing or overheating will rapidly drain cores. In winter some parts of the province average freezing or below at night. Mangoes have recalcitrant seeds which do not survive freezing and drying. Many roads were built to resist rain, freezing and flooding.
