Four distinct Northeast US heat wave circulation patterns and associated mechanisms, trends, and electric usage

نویسندگان

چکیده

Abstract Northeastern US heat waves have usually been considered in terms of a single circulation pattern, the high-pressure typical most occurring other parts world. However, k-means clustering analysis from 1980–2018 shows there are four distinct patterns Northeast wave daily circulation, each which has its own seasonality, heat-producing mechanisms (associated moisture, subsidence, and temperature advection), impact on electricity demand. Monthly statistically-significant positive trends occur late summer for two early third while fourth pattern statistically significant negative trend summer. These results demonstrate that particular geographic area can be initiated maintained by variety mechanisms, resulting types with impacts potential links to climate change, is an effective tool distinguish these differences.

Rising heat wave trends in large US cities

Exposures to dangerously high temperatures are a public health threat expected to increase with global climate change. Heat waves exacerbate the risks associated with heat exposure, and urban residents are particularly vulnerable to threats of heat waves due to the urban heat island effect. To understand how heat waves are changing over time, we examine changes in four heat wave characteristics...

Should electric fans be used during a heat wave?

Heat waves continue to claim lives, with the elderly and poor at greatest risk. A simple and cost-effective intervention is an electric fan, but public health agencies warn against their use despite no evidence refuting their efficacy in heat waves. A conceptual human heat balance model can be used to estimate the evaporative requirement for heat balance, the potential for evaporative heat loss...
