Assessing the Economic Impacts of Weather and Value of Weather Forecasts

Understanding the socio-economic impacts of weather provides a basis for prioritizing actions to mitigate and respond to weather events and understanding the value of improvements in weather forecasts. In this talk I’ll discuss four different topics in the economics of weather and weather forecasts: (1) the economic impacts of weather, (2) the value of current forecasts, (3) the value of improved forecasts, and (4) the value of research to improve forecasts.

Is blocked atmospheric flow a prerequisite for extreme European heat waves in summer?

Atmospheric blocking is a large-scale mid-latitude circulation phenomenon characterized by a persistent anticyclone that interrupts the typically westerly flow. Atmospheric blocking can cause extreme near surface temperature conditions either by the advection of anomalously cold or warm air in the outer region of the block or by anomalies in the surface radiative budget in the center of the block. Summertime blocking conditions were closely linked to the 2003 European heat wave centered in France and the 2010 Western Russia heat wave.

The humid and semi-arid area of the Argentinian Pampas has experienced marked inter-decadal climate variability and significant increases in annual precipitation until recently. Recent increases in precipitation have expanded the boundary of rainfed agriculture towards drier regions and contributed to major changes in land use. However, it is unclear whether the climatic variations form part of a longer term gradual trend or arise from "regime shifts" which would make these evolutions in land use unsustainable if the climate returns to a drier epoch.

Atmospheric organics, ultrafine aerosols, CCN and climate

Organic aerosol is responsible for a significant fraction of atmospheric aerosol mass, yet the impact of these organics on the climate effects of aerosols is still uncertain.  In this talk, we will explore two questions relevant to organics and the climate impacts of aerosols: (1) How does the condensational behavior (i.e. stick irreversibly to the surface area vs.

Oceans, Atmospheric Chemistry and Climate: novel chemistry in the tropical troposphere

Oceans cover 70% of the Earth surface, yet ocean emissions of organic carbon molecules (gas- and aerosol phase) are currently estimated to be 1-2 orders of magnitude smaller than the homologue emissions from land. Thus the ocean is believed to be a net receptor for organic carbon that is emitted over land. Recent our observations of very short-lived and very water soluble oxygenated hydrocarbons -like glyoxal- in the remote marine boundary layer (Sinreich et al., 2010, ACP) and iodine oxide in the tropical free troposphere (Dix et al., 2013, PNAS) remain unexplained by atmospheric models.
