Research and Progress in Forest Meteorology

In the past 20 years,much progress has been made in meteorological research.To sum up,the research trend has the following features:(1) Since 1970s,the emphasis onresearch has been shifted from the effect of forest on local weather to its effect on regionalclimated,even on global climate.The preliminary research results show that the regionalclimate and the global climate are in fluenced by forests,but the extent and magnitude oftheir influence need further deep research.(2) Today the "hotly pursued" subject is therelation of forests with climatic change,especially the greenhouse effect,and the global weather becoming warmer and the climatic change associated with it.At present based onvarious global at mospheric circulation models to forcast the temperature and precipitation incoming time,research is conducted to estimate the effect of this forcasting on the varioustree species and different categories of forests.However,due to wide differences and inaccu-racy of the forcasting by various models,the forcasting of the effect of climatic change onforests is arbitrary and unreliable.Hence such research is still in the initial groping stage.(3) The relation of forests to atmospheric polution and fire is also a subject to which allcountries attach triportance.The focal point in the former is to study the mechanism ofdamage done to forests by atmospheric polution.That of the latter is shifted from theresearch on mechanism to simulation and applied research.(4) All countries attach greatimportance of research means and the development of observatory equipment.The research means of the developed countries have advanced from manual observation to the wire and wireless remote control,satellite remote sensing and air observation,with the resultant dataread into computer to be processed,analysed and simulated.
