RANAU: An unusual ice-like phenomenon was reported on Mount Kinabalu on Oct 11, with small white pellets scattered across steps and walkways, drawing attention to the distinctive weather conditions at Sabah’s highest peak.
The phenomenon, described as “ice rain”, was observed in the mountain area, where temperatures can drop considerably compared with those in the lowlands.
Mt Kinabalu, which rises approximately 4,095 metres above sea level, experiences weather conditions that differ significantly from those in surrounding areas due to its elevation and terrain.
However, the exact nature of the ice-like formations has yet to be established through official meteorological confirmation.
Depending on the prevailing atmospheric conditions, the formations could be hailstones, ice pellets or ice accumulated on exposed surfaces.
Hail forms when water droplets are carried upwards by strong air currents within thunderstorm clouds into freezing regions of the atmosphere. The droplets freeze and grow as they encounter supercooled water before eventually falling to the ground.
Ice pellets, meanwhile, form when frozen precipitation falls through atmospheric layers with suitable temperature conditions, while ice can also accumulate on exposed surfaces when moisture freezes in sufficiently cold conditions.
The distinction is important, as not every ice formation observed in mountainous areas is necessarily evidence of hail or freezing rain.
Mt Kinabalu’s elevation and steep slopes influence local weather patterns. Moist air rising along the mountain cools as it ascends, potentially contributing to cloud formation and precipitation when atmospheric conditions are favourable.
Temperatures can also vary significantly according to altitude, exposure and changing weather conditions, making the mountain environment particularly sensitive to fluctuations in temperature and moisture.
The reported phenomenon highlights the diverse natural conditions found on Mt Kinabalu, which is not only a major climbing destination but also an important natural environment for scientific observation and study.
For climbers, mountain guides and other visitors, unusual weather conditions can pose safety risks. Wet or icy steps and walkways may become slippery, increasing the risk of falls, particularly along steep or exposed sections of the route.
Visitors are advised to follow instructions from mountain guides and park personnel, exercise caution on slippery surfaces and remain alert to changing weather conditions.
The incident underscores the importance of understanding and respecting Mt Kinabalu’s unpredictable mountain weather, where conditions can differ significantly from those experienced in the surrounding lowlands.
