An analysis of the prevalence of heat waves in the United States
between 1948 and 2015
Evan M. Oswald
09 May 2018
Abstract
Unusually hot weather is a major concern to public health as well as
other systems (e.g. ecological, economical, energy). This study
utilized spatially continuous and homogenized observational
surface-climate data to examine changes in the regularity of heat
waves in the continental United States (US). This included examination
of heat waves according only to daytime temperatures, nighttime
temperatures, and both daytime and nighttime temperatures. Results
confirmed strong increase in the prevalence of heat waves between the
mid-1970s and dataset end (2015), and that increase was preceded by
mild decrease since dataset beginning (1948). Results were unclear
whether the prevalence of nighttime or simultaneous daytime-nighttime
heat waves increased the most, but were clear that increases were
largest in the summer. The largest gains occurred in the
West/Southwest, and a "warming hole" was most conspicuous in the
Northern Plains. The changes in heat wave prevalence were similar to
changes in the mean temperatures, and more so in the daytime heat
waves. Daytime and nighttime heat waves coincided with one another
more frequently in recent years than they did in the 1970s. Some parts
of the US (Pacific Coast) were more likely then other parts to
experience daytime and nighttime heat waves simultaneously. While
linear trends were not sensitive to climate dataset, trend estimation
method, or heat wave definition; they were mildly sensitive to the
start/end dates and extremely sensitive to climate base period method
(fixed in time or directly preceding any given heat wave).

An analysis of the prevalence of heat waves in the United States
between 1948 and 2015
There has been a "strong increase" in the prevalence of heat waves in
the US between the mid-1970s and 2015, a new study finds. Analysis of
observed data show that increases in heatwave frequency are similar
for both daytime and nighttime, but largest in summer. Looking at
different regions, the findings suggest the biggest heatwave increases
have occurred in the west and southwest, while the Pacific Coast was
most likely to experience daytime and nighttime heatwaves
simultaneously. -- Journal of Applied Meteorology and Climatology
Consequences of 1.5#C and 2#C global warming levels for temperature and precipitation changes over Central Africa
New research explores the likely changes in temperature and rainfall
changes over Central Africa at 1.5C and 2C of warming above
pre-industrial levels. Based on a collection of 25 regional climate
model simulations, the findings suggest the region will warm at a
faster pace than the global average, with "a tendency towards
decreasing seasonal precipitation in March-May, and a reduction of
consecutive wet days". As a result, "there are obvious advantages to
reduce global warming to 1.5#C relative to 2#C in regard of the
reduced frequency and magnitude of precipitation extremes", the
researchers conclude. -- Environmental Research Letters
