It is presented that indirect assimilation experiment of CMW data from TCFM method improves effectively not only on vertical velocity field but for precipitation.4 Based on theory analysis, E-Ir relationship is brought forward with two electrification mechanisms. One is inductive mechanism, i.e., cloud particles collide with precipitation particles then flick away, the other is noninductive mechanism because of different temperature, i.e., bigger supercooled cloud particles collide and freeze with hail particles combined with ice scraps. By means of CINRAD and FY2C data assimilation, precipitation intensity Ir can be obtained, then electric field intensity E, discharge time and locations can be achieved with supposed threshold 300KV/m. Though it can not distinguish between IC (Intra-Cloud) lightning and CG (Cloud-to-Ground) lightning, results are still comparable to LLS observations.5 Example analysis shows that the relationship between precipitation data from AMS and CG data from LLS is not very clear.

In this observational study, 65 children were treated with SLIT with a build-up phase of 11 days, culminating in a peak dose of 300 IR, and followed by a maintenance phase of 300 IR three times weekly. There were 51 boys and 14 girls; age range was 38 to 80 months (median age, 60 months). Allergens used were house dust mites in 42 patients, grass pollen in 11, olive pollen in five, Parietaria pollen in four, and cypress pollen in three patients. Adverse reactions and changes in the treatment schedule were compared in children aged 38 to 60 months vs those aged 61 to 80 months.
