Physical Processes Involved in the 1988 Drought and 1993 Floods in North America
TLDR
In this paper, an analysis of the spring-summer 1988 drought and 1993 floods over North America reveals a reversal in the sign of anomalies in several fields, implying a large-scale switch in the anomalous tropical heating and forcing of extratropical quasi-stationary waves in the atmosphere.Abstract:
An analysis of the spring–summer 1988 drought and 1993 floods over North America reveals a reversal in the sign of anomalies in several fields. Large sea surface temperature anomalies of opposite signs existed in the tropical Pacific with strong La Nina conditions in 1988 and a mature El Nino in 1993. The distribution of tropical convection in the convergence zones and associated latent heating of the atmosphere were correspondingly altered, implying a large-scale switch in the anomalous tropical heating and forcing of extratropical quasi-stationary waves in the atmosphere, influencing the subtropical jet stream over the North Pacific and across North America. In 1988 the jet stream and the closely related storm track of high-frequency disturbances in the upper troposphere were displaced into Canada well north of the normal location—the farthest north of any year from 1979 to 1993. In 1993 a broader jet stream and the storm track were displaced well south of normal to a more springlike location a...read more

Investigating soil moisture-climate interactions in a changing climate: A review
Sonia I. Seneviratne,T. Corti,Edouard Davin,Martin Hirschi,Eric B. Jaeger,Irene Lehner,Boris Orlowsky,Adriaan J. Teuling +7 more
TL;DR: In this paper, the authors provide a synthesis of past research on the role of soil moisture for the climate system, based both on modelling and observational studies, focusing on soil moisture-temperature and soil moistureprecipitation feedbacks, and their possible modifications with climate change.

The Changing Character of Precipitation
TL;DR: In this article, precipitation intensity, duration, frequency, and phase are as much of concern as total amounts, as these factors determine the disposition of precipitation once it hits the ground and how much runs off.

Changes in precipitation with climate change
TL;DR: There is a direct influence of global warming on precipitation as mentioned in this paper, as the water holding capacity of air increases by about 7% per 1°C warming, which leads to increased water vapor in the atmosphere.
