Use of self organizing map to identify precipitation patterns and assess their impact on hydrographic basins in Brazil

open access: yesRBRH, 2022
In this study, we used neural networks known as self-organizing maps (SOMs) to identify clusters of spatial synoptic precipitation patterns. These clusters were compared with the precipitation regime of the ten main hydrographic sub-basins in Brazil ...

Toward an estimation of the relationship between cyclonic structures and damages at the ground in Europe [PDF]

open access: yes, 2009
Cyclonic systems dominate European and Mediterranean meteorology throughout the year and often induce severe weather in terms of heavy and/or long-lasting precipitation with related phenomena such as strong winds and lightning.

Major heavy rainfall events in China from April to October in 2021

open access: yes暴雨灾害
Based on the daily precipitation data of 2, 424 stations and conventional weather chart data in mainland China in 2021, a statistical analysis of the main heavy rain weather processes from April to October of that year was conducted. The main influencing

High altitude bird migration at temperate latitudes: a synoptic perspective on wind assistance. [PDF]

open access: yesPLoS ONE, 2013
At temperate latitudes the synoptic patterns of bird migration are strongly structured by the presence of cyclones and anticyclones, both in the horizontal and altitudinal dimensions.

Spatial variability in correlation decay distance and influence on angular-distance weighting interpolation of daily precipitation over Europe [PDF]

open access: yes, 2009
Angular-distance weighting (ADW) is a common approach for interpolation of an irregular network of meteorological observations to a regular grid. A widely used version of ADW employs the correlation decay distance (CDD) to (1) select stations that should

Comparative analysis of two flow decomposition approaches and their applications in diagnosing water vapor in extreme precipitation events over Xinjiang province, China

open access: yesFrontiers in Earth Science, 2022
Water vapor flux divergence under the terrain-following coordinate system is decomposed into slow and fast manifolds with the adoption of the Barnes filter method and the synoptic approach based on the Helmholtz theorem in this study.
