Grasshopper populations were high but decreased drastically by summer. In the following dry springs of 19 annual weedy Vegetation was sparse and stunted. In two '2-year periods (1953-58) with good rainfall, the spring vegetation was abundant and grasshoppers increased. Results indicate that rain- fall from October 1 to March 31 had a direct effect on vegetation and an indirect effect on grasshopper populations. Raindrops Keep Fallin on My Head by John Farnham, released 01 March 1980 Raindrops keep falling on my head Im just like a guy whose feet are too big for his bed Nothin´ seems to fit Those raindrops are falling on my head, they keep falling So I just did me some talking to the sun And I said I didn´t like the way he got things done Sleeping. were made in spring and summer and grasshopper counts were made biweekly. A rain gauge was located in each sub area. Four sub areas of Ash Creek Flat with sparse-to-moderate short-grass associations were used. Read moreįrom 1953 through 1960 a study was made on the San Carlos Apache Indian Reservation to determine the effects of fall and winter precipitation and the response of range plants to weather conditions on populations of spring-hatching grasshoppers. ©, 2014, Guangxue Jingmi Gongcheng/Optics and Precision Engineering.

The obtained results provides a basis for research of the performance of ship free space laser communication.

The results show that the model is reasonable and results of the model is coincided basically with that of the experiments.

Based on the raindrop size distribution, a mathematical model of the attenuating effect of rain's blotting-out on the ALC is presented, and the transmitting distance of ALC and the attenuation of the light intensity are calculated. its a great, optimistic tune about facing up to your problems and doing whatever you can to make things better and always realizing that things could be worse. By which, the phenomena that the ALC is achieved within a certain distance in heavy rains is well explained. mainly, especially the overlapping effect between the projecting areas of rain drops on a receiver. This paper points out that the free space laser communication in raining is influenced by the blotting-out effect of the rain drops.
However, most of the research work focus on the discussion on the scattering attenuation of laser beams caused by atmospheric effects. Weather conditions and atmosphere have greater influence on the free space Atmospheric Laser Communication (ALC) between the ships.
