Polar Weather

See how low sunlight, ice, wind, and darkness shape polar weather.

About Polar Weather

Polar weather is driven by low solar angles, long winter darkness, reflective snow and ice, cold air, strong winds, and interactions with surrounding oceans. Conditions can change rapidly and remain dangerous even in summer.

Antarctica — AntarcticaAntarctica is Earth's coldest continent and is covered by a huge ice sheet.

Polar Bear — Polar BearPolar bears are Arctic marine mammals that depend heavily on sea ice.

Emperor Penguins — Emperor PenguinsEmperor penguins survive the extreme cold of Antarctica.

Iceberg — IcebergIcebergs are floating pieces of freshwater ice that broke from glaciers or ice shelves.

Extreme Cold

Antarctica holds the lowest directly measured surface air temperatures on Earth.

Wind

Dense cold air can race downhill from high ice sheets.

Blizzards

Blizzards combine strong wind with snow or blowing snow.

Temperature Inversions

Cold dense air often settles near the surface.

Polar Night

Winter darkness allows the surface to lose heat for long periods.

Polar Summer

Summer brings continuous or nearly continuous daylight.

Forecasting

Weather stations, satellites, balloons, ships, aircraft, and automatic sensors observe polar weather.

Safety

Cold injuries and whiteout conditions can become life threatening.

Extreme Cold

Interior elevations are especially cold because the air is thin, dry, and far from ocean moderation.

Wind

These katabatic winds can become extremely strong along parts of Antarctica.

Blizzards

Visibility can collapse even when little new snow is falling.

Temperature Inversions

This can create temperature profiles opposite to the usual pattern.

Polar Night

At the poles, the Sun remains below the horizon for months.

Polar Summer

Despite long days, the Sun remains low in the sky and surfaces reflect much of its energy.

Forecasting

Remote conditions make observations difficult and expensive.

Safety

Polar field teams use specialized clothing, shelters, navigation, communication, and strict travel planning.
