Irregular weather is destabilizing the soil that supports railroad tracks, roads, buildings and pipelines.
Last year fire storms raged across California. Similar conditions could become more likely for Australia.
Giovanni is interested in how meteorological processes operate at multiple spatial and temporal scales to control air pollution events, and how this influence is mediated by topographic variation and characteristics of the urban environment. His current r
Extreme fire risk will overlap with weather patterns to create fire tornadoes more often under climate change.
