PETALING JAYA: Just because two countries are situated next to each other it does not automatically mean their ultraviolet index (UVI) will be the same at any given point of time, says the Malaysian Meteorological Department (MetMalaysia).
Its director-general Muhammad Helmi Abdullah said geographical location, ozone layer thickness, weather conditions and atmospheric factors such as cloud cover and pollution can affect the intensity of ultraviolet rays hitting the Earth’s surface.
