Organizing all of those extremes into one index is a challenge. Results. The CVI maps exposure (that is whether the district is prone to extreme weather events), sensitivity (the likelihood of an impact on the district by the weather event), and adaptive capacity (what the response or coping mechanism of the district is). 4 Responses to The NOAA Climate Extremes Index. In this article, we . The CEI is a spatially sensitive index that uses percentile-based thresholds rather than absolute values . The Associated Press analyzed the data and found that exposure to extreme heat has tripled and now affects about a quarter of the world's population. One of the greatest impacts of climate variability and climate change occurs through changes in the frequency and severity of extreme events. To meet this societal need, the world climate . This shows that while extreme weather events do not occur every season, a long-term trend towards a more extreme climate can be observed. Combined Climate Extreme Index Overview. Changes in the area of Australia experiencing concurrent temperature and rainfall extremes are investigated through the use of two combined indices. In contrast, a value of 100% would mean that the entire country experienced extreme conditions throughout the period of record for all of the indicators, a virtually impossible scenario. The goal of this diagnostic is to compute time series of a number of extreme events: heatwave, coldwave, heavy precipitation, drought and high wind. A 1°F increase leads to 4 percent more water vapor in the atmosphere, strengthening downpours.
