The Southern Hemisphere Blocking Index Revisited

open access: yesAtmosphere, 2022
An updated climatology for the occurrence of blockings in the Southern Hemisphere (SH) using daily reanalysis data from 1948–2021 is presented. Geopotential height (z) at 500 hPa was the working variable. The blocking index (BI) was defined for every 2.5°

Construction of Air-sounding-profile System Based on Foundation-remote-sensing Equipment

open access: yes应用气象学报, 2022
Radiosonde data are indispensable for severe convective weather forecast because they can not only reflect the temperature and humidity structure and dynamic characteristics of local atmosphere, but also indicate the favorable conditions of convection ...

A New Method for Estimating Tropospheric Zenith Wet-Component Delay of GNSS Signals from Surface Meteorology Data

open access: yesRemote Sensing, 2020
A new concept is proposed for estimating the zenith wet delay (ZWD) and atmospheric weighted average temperature by inputting the temperature, total pressure, and specific humidity from surface weather data.

Research on a Quality Control Method for L Band Second-Level Radiosonde toward Assimilation Applications

open access: yesGaoyuan qixiang, 2022
Since 2003, the World Meteorological Organization (WMO) proposed and coordinated a switch from traditional radiosonde format (TAC code) to second-resolution binary (BUFR) report, which leads the assimilation of second radiosonde data in numerical ...

Further examination of the anomaly in the radiosonde data of Ahmedabad

open access: yesMAUSAM, 1989
In the preceding paper attention was drawn to systematic errors in the radiosonde data of Ahmedabad leading to serious anomalies in the pressure-wind relationship in the Bombay-Ahmedabad-Jodhpur sectors. Since then we have examined the monthly mean aerological data of the three stations for the 18-year period 1965-1982.

Analysis on Characteristics of Radiosonde Bias Using GPS Precipitable Water Vapor [PDF]

open access: yesJournal of Astronomy and Space Sciences, 2010
As an observation instrument of the longest record of tropospheric water vapor, radiosonde data provide upper-air pressure (geopotential height), temperature, humidity and wind. However, the data have some well-known elements related to inaccuracy.

Surface and Tropospheric Climatic Trends in the Galápagos Archipelago Based on the Galápagos Archipelago Refined Analysis Dataset

open access: yesInternational Journal of Climatology, EarlyView.
The Galápagos Archipelago's near‐surface climate is primarily influenced by interannual El Niño‐Southern Oscillation variability, with no statistical evidence for long‐term trends in air temperature, humidity, or precipitation. While tropospheric warming and increased atmospheric stability are observed, these trends are largely decoupled from near ...

Towards improving Arctic mixed‐phase cloud representation in the ECMWF model using MOSAiC observations

open access: yesQuarterly Journal of the Royal Meteorological Society, EarlyView.
Abstract The presence of Arctic clouds plays a crucial role in the evolution of the surface temperature of Arctic sea ice. However, large biases in cloud representation remain in state‐of‐the‐art weather and climate models. In this study, we use observational data from the one‐year Arctic ship campaign Multi‐disciplinary drifting Observatory for the ...
