Meteorological stations

The system is designed with two servers connected in a cluster, so it has high stability. Alerts are delivered to users quickly using push notification technology, suitable for personal computers and iOS and Android mobile devices. The system is in line with the trend of Vietnamese people using mobile devices to monitor weather information today. Therefore, this will be an effective source of extreme weather warnings that VNMHA can use.

Cotton is one of the principal commercial crop and it is the back bone of national economy of our country. Cotton remains the most miraculous fiber and is still nature’s wonder fiber. Cotton is grown all around the globe, and is traded internationally as well. The production is influenced by the repeated out breaks of pest and diseases and these are the major factors responsible for lower yield of cotton in India.

On 9 December 2018, a heavy rainfall event occurred in central Viet Nam, and at Da Nang, a record–breaking rainfall of 972 mm was observed in 24 hours. The operational precipitation analysis at the Viet Nam Meteorological and Hydrological Administration (VNMHA) on the day considerably underestimated the intense rains. We checked causes of underestimation and modified the precipitation analysis by revising the use of observation data from Automated Weather Stations (AWS) and meteorological radar data.

The GSMaP Rainfall (Global Satellite Mapping of Precipitation) data (GSMaP_NOW and GSMaP_MVK) have been used for precipitation analysis at Vietnamese National Center for Hydro–Meteorological Forecasting (NCHMF) since October 2019. This study verified the quality of rainfall estimates of GSMaP_NOW, GSMaP _MVK and Himawari–8 based on 6 hourly rain gauge data from 184 SYNOP stations for a 4–month period from October 2019 to January 2020.

This paper presents a comparison of four different rainfall data sources: rainfalls from TRMM and GPM satellites, PERSIANN system, and in-situ measurements at meteorological stations. The data from TRMM and GPM satellites have been used by many countries. The comparisons of rainfall data from satellites or the online metadata system with in-situ measurement present a similar pattern of spatial distribution between these resources but the amounts of rainfall are quite different.

Field experiment was conducted during 2011-2015 at Sisal Research Station (22.041°N, 84.295°E, 267 m above mean sea level, AMSL), Bamra, Odisha, India to study the effect of drip-irrigation and micronutrients (Zn and B) on growth, fibre yield, water use efficiency, nutrient and micronutrient content in sisal (Agave sisalana Perr. Ex Engelm.). It was observed that interaction of drip-irrigation @ 4 l/hr for 2 hrs at 2 weeks interval during 14-23 standard meteorological week (SMW) x micronutrients (zinc sulphate @ 20 kg + borax 15 kg/ha) produced the longest leaf (97.2.

The agricultural drought has become a major concern worldwide because of its severe effect on the productivity of rain-fed crops and direct effect on service as well as per capita income. These agricultural droughts occur due to short-term moisture stresses. This work was carried out to analyze droughts in the Banswara region of Rajasthan using Effective Drought Index (EDI). Out of the 11 rain gauge station selected in the study, it was found that according to EDI, a meteorological drought of maximum severity -34.

The study was conducted in Shipra river basin to determine actual evapotranspiration in the area. Long term daily meteorological data including rainfall, maximum temperature, minimum temperature, relative humidity, wind speed and sunshine hours of Indore IMD station was used as input data in CROPWAT Model 8.0. The potential evapotranspiration was converted into actual evapotranspiration by using the crop coefficient. Reference evapotranspiration is a measure of evaporative demand, while the crop coefficient accounts for crop characteristics and management practices (e.g.
