太阳辐射的强弱与许多因子有关，其中最主要的是太阳高度角和大气透明度。当太阳高度角相等时，大气透明度是决定太阳辐射的关键因子。随低云量增多，多太阳辐射的削弱越大，到达地面的太阳辐射越少；水汽压越大，说明大气中水汽含量越多，对太阳辐射的削弱越大。
空气中的热量主要来源于太阳辐射，太阳辐射到达地面后，一部分被反射，一部分被地面吸收，使地面增热；地面再通过辐射、传导和对流把热传给空气，一般太阳辐射与气温呈正相关关系，即太阳辐射减少，地面吸收的热量减少，气温降低；太阳辐射增多，气温就会升高。但是海口的近几年气温呈升高趋势，与太阳辐射的变化趋势截然相反，到达地面的太阳辐射减少而气温升高，这是由于太阳辐射减少对地面的降温作用远远小于城市热岛效应引起的升温作用，才造成气温升高。

The intensity of solar radiation associated with many factors, foremost among them is the solar altitude and atmospheric transparency. When the Sun's elevation angle are equal, atmospheric transparency the key factor is to determine the solar radiation. With increasing low cloud cover, solar radiation to weaken more, less solar radiation reaches the ground; larger vapor pressure, suggests the greater levels of water vapor in the atmosphere, solar radiation to weaken more.Heat in the air come from solar radiation, solar radiation reaches the ground and part is reflected, some is absorbed by the ground, bringing the ground thermal ground by radiation, conduction and convection heat to the air, solar radiation and air temperature were positively correlated, which reduce solar radiation, ground absorption of heat reduction, lowering temperatures; increase in solar radiation, the temperature will rise. But an increased trend in sea temperatures in recent years, with diametrically opposite trends in solar radiation, reduction of solar radiation reaches the ground and temperatures rise, this is due to the solar radiation to reduce the cooling effect of the ground much less warming effect caused by the urban heat island effect, could result in higher temperatures.

The intensity of solar radiation is related to many factors, the most important is the solar zenith angle and atmospheric transparency. When the solar zenith angle is equal, the atmospheric transparency is the key factor to determine the solar radiation. With the increase of the low cloud cover, solar radiation weakened more, reach the ground solar radiation less; vapor pressure is that more water vapor in the atmosphere, to solar radiation weakened more.Air heat comes mainly from solar radiation, solar radiation reaching the ground, some is reflected and part is ground absorption, so as to add heat to the ground; ground by radiation, conduction and convection to heat to the air, general solar radiation and air temperature were positively correlated, namely the reduction of the solar radiation, reduce the heat absorbed by the ground, reduce the temperature; solar radiation increased, the temperature will increased. But in Haikou in recent years temperature showed an increasing trend, and solar radiation changes trend, on the contrary, reach the surface solar radiation reduced and elevated temperature. This is due to the reduction of the solar radiation on the surface of the cooling effect is far less than that of the urban heat island effect caused by temperature rise, caused by rising temperatures.
