The coastal area of southern China is frequently affected by marine meteorological disasters,and is also one of the key areas that influence the short-term climate change of China.Due to a lack of observational facilities and techniques,little has been done in this area in terms of operational weather monitoring and scientific research on atmospheric and marine environment.With the support of China Meteorological Administration (CMA) and Guangdong Meteorological Bureau (GMB),the Marine Meteorological Science Experiment Base (MMSEB) at Bohe,Maoming has been jointly established by Guangzhou Institute of Tropical and Marine Meteorology (GITMM) and Maoming Meteorological Bureau (MMB) of Guangdong Province after three years of hard work.It has become an integrated coastal observation base that is equipped with a complete set of sophisticated instruments.Equipment maintenance and data quality control procedures have been implemented to ensure the long-term,steady operation of the instruments and the availability of high quality data.Preliminary observations show that the data obtained by the MMSEB reveal many interesting features in the boundary layer structure and air-sea interaction in such disastrous weather as typhoons and sea fog.The MMSEB is expected to play an important role in the scientific research of disastrous weather related to marine meteorology. 相似文献

Using the data of long-term (1958–2012) actinometric and meteorological observations of the Meteorological Observatory of Lomonosov Moscow State University, the observed and computed long-wave fluxes and the factors defining their variability are estimated. Obtained are the normals and determined are the limits of variability of effective radiation. Analyzed are the peculiarities of atmospheric back radiation. Demonstrated is the trend towards the decrease (in absolute value) in effective radiation caused by the increase in the atmospheric back radiation flux (E a). The trend towards the increase in the atmospheric back radiation is determined by the increase in the values of meteorological parameters: cloudiness, atmospheric moisture content, and temperature. The content of aerosol and carbon dioxide does not affect the long-term variations of E a registered in Moscow. Derived empirical formulae can be recommended for estimating the atmospheric back radiation and effective radiation of the Earth surface using meteorological observations. 相似文献

Convective Scale Structure and Evolution of a Squall Line Observed by C-Band Dual Doppler Radar in an Arid Region of Northwestern China 总被引：1，自引：0，他引：1
A long-lived and loosely organized squall line moved
rapidly across Urumqi, the capital city of Xinjiang Uygur
Autonomous Region of China on 26 June 2005, generating hail and
strong winds. The squall line was observed by a dual Doppler radar
system in a field experiment conducted in 2004 and 2005 by the
Chinese Academy of Meteorological Sciences and the local
meteorological bureau in northwestern China. The 3D wind fields
within the squall line were retrieved through dual Doppler analyses
and a variational Doppler radar analysis system (VDRAS). The
formation and structure of the squall line as well as the genesis
and evolution of embedded convective cells were investigated. During
its life period, the squall line consisted of six storm cells
extending about 100 km in length, and produced hail of about 25 mm
in diameter and strong surface winds up to 11 m s-1. Radar
observations revealed a broad region of stratiform rain in a
meso-β cyclone, with the squall line located to the
west of this. Two meso-γ scale vortices were found within
the squall line. Compared to typical squall lines in moist regions,
such as Guangdong Province and Shanghai, which tend to be around
300--400 km in length, have echo tops of 17--19 km, and produce
maximum surface winds of about 25 m s-1 and temperature
variations of about 8oC this squall line system had weaker
maximum reflectivity (55 dBZ), a lower echo top (13 km) and
smaller extension (about 100 km), relatively little stratiform
rainfall preceding the convective line, and a similar moving speed
and temperature variation at the surface. 相似文献

Soil temperature is a meteorological data directly affecting the formation and development of plants of all kinds. Soil temperatures are usually estimated with various models including the artificial neural networks (ANNs), adaptive neuro-fuzzy inference system (ANFIS), and multiple linear regression (MLR) models. Soil temperatures along with other climate data are recorded by the Turkish State Meteorological Service (MGM) at specific locations all over Turkey. Soil temperatures are commonly measured at 5-, 10-, 20-, 50-, and 100-cm depths below the soil surface. In this study, the soil temperature data in monthly units measured at 261 stations in Turkey having records of at least 20 years were used to develop relevant models. Different input combinations were tested in the ANN and ANFIS models to estimate soil temperatures, and the best combination of significant explanatory variables turns out to be monthly minimum and maximum air temperatures, calendar month number, depth of soil, and monthly precipitation. Next, three standard error terms (mean absolute error (MAE, °C), root mean squared error (RMSE, °C), and determination coefficient (R 2)) were employed to check the reliability of the test data results obtained through the ANN, ANFIS, and MLR models. ANFIS (RMSE 1.99; MAE 1.09; R 2 0.98) is found to outperform both ANN and MLR (RMSE 5.80, 8.89; MAE 1.89, 2.36; R 2 0.93, 0.91) in estimating soil temperature in Turkey.
