Celebrating World Meteorological Day 2025: Honoring the Meteorologists of SANAP’s Overwintering Teams

Each year, on March 23rd, the global community observes World Meteorological Day, commemorating the establishment of the World Meteorological Organization (WMO) in 1950. This day highlights the pivotal role meteorology plays in ensuring the safety and well-being of societies worldwide. In 2025, we focus on the indispensable contributions of meteorologists stationed at the South African National Antarctic Programme’s (SANAP) remote research stations: SANAE IV in Antarctica, Marion Island, and Gough Island.
On this World Meteorological Day, we extend our gratitude to the meteorologists of SANAP’s overwintering teams. Their unwavering commitment and resilience in some of the most challenging environments ensure that we continue to deepen our understanding of Earth’s atmospheric processes, ultimately contributing to the safety and well-being of societies worldwide.
SANAE IV (South African National Antarctic Expedition IV): Located at 71°S, 2°W in Antarctica, SANAE IV. Meteorological observations are conducted year-round, providing critical data on atmospheric conditions in this remote region.
Marion Island: Situated at 46°S, 37°E in the Southern Indian Ocean. The island’s meteorological station collects essential weather data, contributing to climate studies and aiding in the understanding of global weather patterns.
Gough Island: Located at 40°S, 9°W in the South Atlantic Ocean, Gough Island has hosted a South African weather station since 1956. The station conducts hourly climate observations and upper-air ascents, playing a crucial role in monitoring weather systems that can impact South Africa.

Meteorologists assigned to these stations undertake year-long deployments, known as overwintering periods, during which they perform several critical functions:
Surface Observations: Conducting regular measurements of temperature, humidity, wind speed, and other atmospheric parameters to monitor and document local weather conditions.
Upper-Air Observations: Launching weather balloons equipped with instruments to collect data on atmospheric pressure, temperature, and humidity at various altitudes, which is vital for understanding weather patterns and forecasting.
Equipment Maintenance: Ensuring that all meteorological instruments and equipment are calibrated and functioning correctly to maintain the accuracy and reliability of collected data.
Data Management: Recording, analyzing, and transmitting collected meteorological data to the South African Weather Service (SAWS) and other relevant organizations for use in weather forecasting and climate research.
The data collected by SANAP’s overwintering meteorologists contribute significantly to:
Weather Forecasting: Providing accurate and timely data that enhance the precision of weather forecasts, benefiting maritime navigation, aviation, and local communities.
Climate Research: Offering valuable insights into climate variability and change, particularly in the understudied southern hemisphere regions.
Environmental Monitoring: Supporting studies on the interactions between the atmosphere and the unique ecosystems of Antarctica and the sub-Antarctic islands, aiding in the conservation of these fragile environments.

Join Us at ICG 2025 in New Zealand – Call for Abstracts: Geomorphological Insights from the Sub-Antarctic

The International Conference on Geomorphology (ICG) 2025 is set to take place in breathtaking New Zealand, a land renowned for its dynamic landscapes and geological wonders. This global gathering of geomorphologists will provide a platform for cutting-edge discussions on landform processes, climate interactions, and Earth surface dynamics. We invite researchers, early-career scientists, and professionals to contribute to this exciting event by submitting abstracts to the special session:

Geomorphological Insights from the Sub-Antarctic

Description: Sub-Antarctic islands, situated in the remote Southern Ocean, offer a unique geomorphological perspective due to their distinct geographical setting. These cold islands, characterized by both glacial and periglacial processes, provide crucial insights into the historical and ongoing changes in oceanic and atmospheric circulation patterns within the southern hemisphere mid-latitudes. Unlike their northern hemisphere counterparts, these islands experienced a different Last Glacial Maximum (LGM) and complex deglaciation, leading to unique geomorphological features and processes. The landforms of these islands serve as invaluable proxies for understanding landscape responses to climate change. Palaeo-climatic shifts have profoundly influenced geomorphological and cryogenic dynamics, shaping landforms and influencing ecosystem processes. Contemporary climatic changes, such as rising temperatures, moisture fluctuations, and increased frequency of extreme events, pose significant threats to these delicate geomorphological systems. These changes have the potential to push landscape and ecosystem processes beyond their existing environmental thresholds, impacting landforms and biodiversity. This session aims to explore the geomorphological significance of Sub-Antarctic islands and their role as indicators of environmental change. We invite contributions that highlight the geomorphological processes and dynamics that shape the landscape of these Sub- Antarctic Islands. Research focusing on the region’s geomorphological responses to past and present climatic conditions and the possible implications for ecosystem processes are particularly welcome. Emerging researchers are encouraged to submit their work to advance our understanding of these critical sentinel landscapes.
