AR forecasts were also crucial in the Vancouver region during November 2021, following an autumn of heavy rain and mountain snow. Perhaps an AR warning for an upcoming storm can be issued one day sooner, or the rain total can be predicted with even greater accuracy, getting people out of harm's way or increasing water-supply reliability for inevitable dry days to come. Preliminary analysis has shown that AR Recon data improved the prediction and reduced the precipitation forecast error by as much as 50 percent; without it, the predicted rain amount for Big Sur would have been much less than what fell. AR Recon flew more missions every day, firming up indications that the storm would reach AR2 or AR3 levels and would stall, which meant some unlucky coastal region could experience heavy rain for up to a day and a half.

These "urban heat islands" can creep underground as city heat diffuses downward, and basements, subway tunnels and other subterranean infrastructure also constantly radiate warmth into the surrounding earth. Because materials expand and contract with temperature changes, Rotta Loria suspected that heat seeping from basements and tunnels could be contributing to wear and tear on various structures. CITY STREETS, SIDEWALKS and roofs all absorb heat, making some urban zones up to six degrees Fahrenheit hotter than rural ones during the day - and 22 degrees F hotter at night.

The article discusses the impact of stalled and highly bent waves in the jet stream on extreme weather events such as heat waves and flooding. Topics include the use of mathematics from quantum mechanics to explain how resonance in the atmosphere amplifies the bends causing extreme weather events, and the impact of aerosols and in the air and scrubbers from coal plants on the intensity of the weather events.

The article reports on the subtlety of the truth about El Niño and La Niñ climate patterns which often get blame for extreme weather. Topics include the tendency of the media and meteorologist to link extreme weather to the climate patterns, the inconsistency of the climate patterns which failed to bring expected heavy rains to southern California in 2015-2016, and the continued recurrence of El Niños and La Niñs for thousands of years.

Climate change tends to bring out the worst in the weather, be it extreme cold or heat, rain or fire. GRAPH: The absolute number of extreme rainfall events following each extreme fire event will also go up. GRAPH: The absolute number of extreme fire events followed by extreme rainfall is projected to rise. [Extracted from the article]

The article discusses extreme summer and winter weather caused by contortions in the jet streams over North America and Europe. Topics include severe drought and winter weather in Europe and the U.S. between 2010-2014, a study by Shih-Yu (Simon) Wang and colleagues that suggests human-caused global warming reconfigured the jet stream, a greenhouse effect, called Arctic amplification, and connections between the El Nino/Southern Oscillation and the Arctic Oscillation.

The article focuses on the higher frequency of extreme weather disruptions due to climate change facing babies born in 2022, based on a study of combined climate model projections published by Wim Thiery of Vrije Universiteit Brussel in Belgium and his colleagues in the periodical "Science."

Discusses key issues concerning droughts, the recurrent and often devastating feature of the sub-Saharan climate in Africa. Dealing with droughts in ways that will stabilize the region's farm production if leaders were to treat it as recurrent phenomenon; Meteorological, agricultural and hydrological aspects of droughts; Implications on environmental studies and agricultural systems and policies.

The article focuses on published article in periodicals on weather data including examines that during the past hurricane season in the West Indies the U. S. Weather Bureau has carried out a program of upper-air observations.

The author reflects on weather patterns during the winter of 2018 and 2019 and examines how it compares to past climate conditions.

Reports on computer simulations of the weather of an ancient supercontinent called Pangaea. Significance of determining the weather in Pangaea; Formation of Pangaea during the Paleozoic era; Simulations performed by Thomas J. Crowley of the Applied Research Corp., William T. Hyde of Texas A&M University and David A. Short of the U.S. National Aeronautics & Space Administration.

Discusses the two very different factors that contribute to the uncertainty that obscures the course of the weather. Chaotic or random nature of a macroscopic system; Description of subatomic phenomena that relies on probabilistic, quantum-mechanical equations; Inherent limit on the precision with which certain variables can be measured.

A graph is presented of the oceans' surface temperatures from 1910 to 2010, with information on the effect that rising ocean temperatures could have on marine life, currents, and weather patterns.

Reports that researchers have found that the trend towards working on the weekends seems to affect daytime high and nighttime low temperatures. Conclusion that the daily swings in temperature follow a weekly pattern, with the diurnal range being smaller in urban settings; Speculation that soot and sulphate aerosols from motor vehicles and coal-burning plants may be affecting cloud cover.

Lists several books that provide supplementary information for a research article on droughts in Africa published in the June 1987 issue of the 'Scientific American' periodical. Range of issues and subject matter on droughts in Africa that were explored by the books; Authors credits; Publisher information.
