Atmospheric & Ice Shelf Dynamic Simulator
Net Accumulation Gain
Physics Model: Warm sea surface anomalies drive atmospheric rivers toward the polar vortex, amplifying precipitation over the continental plateau. Meanwhile, marine-terminating glaciers discharge ice through calving and basal melting along the coastal edge.
SCENARIO PRESETS
Balance Controls & Mass Budget
Tropical Warmth Anomaly
+1.4 °C
Higher anomalies warm low-latitude oceans and evaporate more atmospheric vapor.
Moisture Transport Rate Multiplier
1.25x
Atmospheric circulation efficiency pushing moisture over the transantarctic interior.
Annual Glacier Discharge & Calving
2155 Gt/yr
Ice lost to icebergs and basal ocean shelf melt (e.g. Thwaites & Pine Island glaciers).
NET ANNUAL MASS BALANCE
+695 Gt
Continent is storing ice, mitigating sea-level rise
Annual Snowfall
2850 Gt
Surface mass accumulation
Glacier Discharge
2155 Gt
Calving & sub-shelf melting
Sea Level Equivalent
