Air Ions And The Study Of Meteorological Factors

With the progress of science and technology and the improvement of people's awareness of environmental protection, air ions in the study has drawn increasing attention. according to the particle size can be divided into large air-ion ion ion, small ion, according to the charge can be divided into positive ions and negative, negative air ion known as air'vitamins','nutrients'and'Environmental Police', as an important indicator for measuring air and the environment. Since studied from August 2006 to January 2007 within six months, ions in the air under different weather conditions change, the more abundant accumulation of the measured data.Research shows :Changes in ion concentration in the air, air ion concentration is no significant change with the seasons change. Anion concentrations are compared by the weather conditions : rain, followed by sunny days and the third is fog, cloudy day minimum. Ions are quite the same : fog and rain, sunny Third, cloudy day minimum. Sunny, anionic ion is higher than that; Also, higher anion ion; Cloudy, anionic ion is below; Fog. anion ion below. Fog from mild to severe fog, air ions marked change in the negative ion concentration has been reduced, The ion concentration is increased. The average of all data found that the ion concentration is higher than the value of anion concentration. Daily air anion concentrations were positively correlated with the daily average humidity. the temperature of the air anion concentrations were negatively correlated with the average daily temperature. Ion concentration and air velocity were not so relevant.The daily average concentration of negative ions with Japan was certainly mean PM10 negative correlation. Small concentrations of anions with the daily average PM10 negative correlation with the Japanese as the highest.I propose a set of small anion concentration parameters for the evaluation of the air quality index system.
