Research on Modeling Weighted Average Temperature Based on the Machine Learning Algorithms

open access: yesAtmosphere, 2023
In response to the nonlinear fitting difficulty of the traditional weighted average temperature (Tm) modeling, this paper proposed four machine learning (ML)-based Tm models.

Performance of Forecasts of Hurricanes with and without Upper-Level Troughs over the Mid-Latitudes

open access: yesAtmosphere, 2020
We investigated the accuracy of operational medium-range ensemble forecasts for 29 Atlantic hurricanes between 2007 and 2019. Upper-level troughs with strong wind promoted northward movement of hurricanes over the mid-latitudes. For hurricanes with upper-

Validation of precipitable water from ECMWF model analyses with GPS and radiosonde data during the MAP SOP [PDF]

open access: yes, 2005
Precipitable water vapour contents (PWCs) from European Centre for Medium-Range Weather Forecasts (ECMWF) analyses have been compared with observations from 21 ground-based Global Positioning System receiving stations (GPS) and 14 radiosonde stations (RS)

Tropospheric Gravity Waves Increase the Likelihood of Double Tropopauses

open access: yesGeophysical Research Letters, 2023
The tropopause region is crucial for the stratosphere‐troposphere exchange (STE) and acts as an indicator of climate change. Double tropopauses (DTs) act to increase the STE process but their driving mechanisms remain an open question.

Assessment of the potential of MERIS near-infrared water vapour products to correct ASAR interferometric measurements [PDF]

open access: yes, 2006
Atmospheric water vapour is a major limitation for high precision Interferometric Synthetic Aperture Radar (InSAR) applications due to its significant impact on microwave signals.

Precipitable Water Vapour Retrieval from GPS Precise Point Positioning and NCEP CFSv2 Dataset during Typhoon Events

open access: yesSensors, 2018
Radiosonde is extensively used for understanding meteorological parameters in the vertical direction. Four typhoon events, including three landfalls (MERANTI, NEPARTAK, and MEGI) and one non-landfall (MALAKAS), were chosen in analysing the precipitable ...

Radiosonde measurements from Neumayer Station (2020-02)

open access: yes, 2021
The meteorological observatory Neumayer typically launches one radiosonde per day around 12UTC. At least weekly the sonde has an ozone sensor attached. Sondes are released from the roof of the station building. The measurement interval of the raw data is
