Recent changes in the diurnal cycle of precipitation over the United States [PDF]

Geophysical Research Letters, 1999
Hourly precipitation data from 1963 to 1993 of the contiguous United States were analyzed for secular trends in the diurnal cycle of precipitation. During the period the winter daytime and nighttime precipitation frequencies and the diurnal amplitude of precipitation frequency increased by ∼30–47% over the Southwest, while the winter precipitation ...

A framework to evaluate and identify development requirements for land‐surface models at km‐scale resolution: Application to a semi‐arid and mountainous region

Quarterly Journal of the Royal Meteorological Society, EarlyView.
This article provides a first evaluation of land‐surface models at the km‐scale resolutions at which they are used in weather and Earth‐system models. At these resolutions, the lateral transfers of water that organize landscapes play an important role in predicting evaporation correctly. Riparian processes and human water management for irrigation need

Seasonal and Diurnal Variations of Lightning Activity Over West Sumatra and Its Correlation with Precipitation Type

Makara Journal of Science, 2018
Seasonal and diurnal variations of lightning activity over West Sumatra have been investigated using observations of Tropical Rainfall Measuring Mission–Lightning Imaging Sensor (TRMM–LIS) over a 16-year period.

Addressing Biases in Ice Jam Observations by Integrating Multi‐Source Data in a Forested Fluvial Landscape, Southern Quebec

River Research and Applications, EarlyView.
ABSTRACT Exhaustive long‐term and large‐scale ice jam records are scarce in most cold river environments. Many discrete events occur in small, sparsely populated river systems and are poorly represented in open‐source databases. These observation biases are transferred to predictive models of ice jams and the collective understanding of their formation

Evaluation of convection-resolving models using satellite data: The diurnal cycle of summer convection over the Alps

Meteorologische Zeitschrift, 2016
Diurnal moist convection is an important element of summer precipitation over Central Europe and the Alps. It is poorly represented in models using parameterized convection.

Irrigation in the North China Plain regulates the diurnal cycle of precipitation and regional water cycle

Climate Dynamics
Abstract Irrigation, a significant human activity, impacts regional water cycles and climate. The effect of irrigation on the diurnal cycle of precipitation (DCP) remains ambiguous. In this study, we investigate irrigation's effects on the DCP and assess its contribution to precipitation in North China, utilizing a regional model coupled with a

Application of a Presumptive Standards Approach to Evaluate Environmental Flows in a Highly Regulated River Basin

River Research and Applications, EarlyView.
ABSTRACT The presumptive standards approach to environmental flows offers a method to develop interim guidelines for ecological and social‐cultural flow needs. The approach is based on deriving acceptable percent‐of‐flow limits based on naturalised flows (the absence of depletion or alteration of flow), and it can be an effective precursor to a full ...

Climate‐Driven Mangrove Dieback and Recovery: A Case Study in Albert and Leichhardt Rivers, Australia

Remote Sensing in Ecology and Conservation, EarlyView.
Cycles of dieback and recovery drove mangrove forest dynamics at the Albert and Leichhardt Rivers (Gulf of Carpentaria, Queensland, Australia) over 36 years (1987–2023). Landward margins were the most affected by reduced tidal inundation when the alignment of low lunar declination suppressed tidal range and extreme El Niño phases lowered mean sea level.

Long-term trends in the diurnal cycles of precipitation frequency in Japan

Papers in Meteorology and Geophysics, 2005
Long-term changes in diurnal variation patterns of precipitation frequency were analyzed using visual data (ww) for 42 years (1961 to 2002) in Japan. The precipitation frequency relative to the daily mean was found to have increased in the nighttime and decreased in the daytime at a rate of the order of 0.01 per decade. This change was observed for all

Wildlife temporal behaviors in response to human activity changes during and following COVID‐19 park closures

Wildlife Biology, EarlyView.
With urbanization reducing the amount of available wildlife habitat, and outdoor recreation increasing the human activity within wildlife habitats, it is important to understand the effects of human activity on animal behavior. This study examined how the reduction in human presence in urban parks in Gainesville, Florida, affected the temporal ...
