Rainfall characteristics of north west alluvial plain zone of Bihar

open access: yesJournal of Agrometeorology, 2009
Rainfall data for the period 1960-2005 is used to analyze the probability of occurrence of deficit /normal / excess rainfall. The mean annual rainfall is 1200 mm with 28 percent variability; with standard deviation of 336 mm.

Using the Firefly optimization method to weight an ensemble of rainfall forecasts from the Brazilian developments on the Regional Atmospheric Modeling System (BRAMS) [PDF]

open access: yesAdvances in Geosciences, 2013
In this paper we consider an optimization problem applying the metaheuristic Firefly algorithm (FY) to weight an ensemble of rainfall forecasts from daily precipitation simulations with the Brazilian developments on the Regional Atmospheric Modeling ...

Flare forecasting at the Met Office Space Weather Operations Centre [PDF]

open access: yesSpace Weather, 15, 577-588 (2017), 2017
The Met Office Space Weather Operations Centre produces 24/7/365 space weather guidance, alerts, and forecasts to a wide range of government and commercial end users across the United Kingdom. Solar flare forecasts are one of its products, which are issued multiple times a day in two forms; forecasts for each active region on the solar disk over the ...

Implementation of an Adaptive Bias‐Aware Extended Kalman Filter for Sea‐Ice Data Assimilation in the HARMONIE‐AROME Numerical Weather Prediction System

open access: yesJournal of Advances in Modeling Earth Systems, 2021
Sea ice surface temperature is an important variable for short‐range numerical weather prediction systems operating in the Arctic. However, when provided by numerical sea ice models, this variable is seldomly constrained by the observations, thus ...

Weather Forecasts in England [PDF]

open access: yesNature, 1914
MR. MALLOCK'S position in the scientific world is one of distinction and his letters on the subject or weather forecasts in England, which appeared in NATURE of February 26 and June 4, can, accordingly, scarcely fail to be regarded by many who are unfamiliar with the circumstances as reflecting injuriously upon the department of the public service ...

An explicit method of mesoscale convective storm prediction for the central region of Russia [PDF]

open access: yesAdvances in Science and Research, 2018
This work presents simulation results of the storm observed on the 13–14 July 2016 over the Central region of Russia. The Cumulonimbus cloud (Cb) electrification model coupled with the numerical weather prediction model WRF-ARW were used for this ...
