A diagnostic framework is introduced in which anomalous zonally-averaged Rossby wave-activity injection into the stratosphere is decomposed into a contribution solely from zonally-confined upward-propagating Rossby wave packets and another from interaction of the wave packets with the climatological stratospheric planetary waves. To pinpoint the tropospheric sources of the wave packets, a parti...

Distribution of hydrological parameters is varied under contrasting meteorological conditions. However, how to determine the most suitable on a predefined condition challenging. To address this issue, prediction method based classification established, which conducted by using standardized runoff index (SRI) value identify three categories, i.e., dry, normal and wet years. Three different simul...

In this paper, a novel typhoon intensity classification and estimation network (TICAENet) is constructed to recognize intensity. The TICAENet model based on the LeNet-5 model, which uses weight sharing reduce number of training parameters, VGG16 replaces large convolution kernel with multiple small kernels improve feature extraction. Satellite cloud images typhoons over Northwest Pacific Ocean ...

Looking through the history, people have always been associating suicide with weather conditions, trying to understand and identify the relationship between meteorological factors and suicide. The aim of this study was to determine and analyze the meteorological conditions in the time of attempted or committed suicides, and examine the possible link between the changes of meteorological factors...

(G) and observed discharge (Q), whereas the other data-driven model, ANN-Ensemble (ANN-E), and the two conceptual models, HBV and GR4J, use forecasted meteorological inputs (P and PET), whereby we employ ensemble seasonal meteorological forecasts. We compared low flow forecasts without any meteorological forecasts as input (ANN-I) and five different cases of seasonal meteorological forcing: (1)...

An intense orographic precipitation event on 5 January 2013 is analyzed using a polarimetric C-band radar situated north of the Alps. The radar is operated at the meteorological observatory Hohenpeißenberg (MHP, 1006 m a.s.l. – above sea level) of the German Meteorological Service (DWD). The event lasted about 1.5 days and in total 44 mm precipitation was measured at Hohenpeißenberg. Detailed h...
