The precipitation increase verification method includes: obtaining a first piece of observation information from an upwind area after a seeding experiment; obtaining a second piece of observation information from a downwind area; comparing the first piece of observation information with the second piece of observation information, and thus determining whether or not the first piece of observation information and the second piece of observation information fall within a linear scope; and determining that an effect resulting from the seeding experiment can be proved when the first piece of observation information and the second piece of observation information fall within the linear scope. ## Claims ### Claim 1 A method of verifying an increase in precipitation, comprising: spraying artificial cloud seeds for a seeding experiment; obtaining, by an aerial observation equipment including a cloud condensation nucleus counter, a cloud combination probe, and a precipitation imaging probe, a first piece of observation information from an upwind area after the seeding experiment; obtaining, by the aerial observation equipment, a second piece of observation information from a downwind area after the seeding experiment; comparing, by a verification system including the aerial observation equipment, the first piece of observation information with the second piece of observation information, and thus determining, by the verification system, whether or not the first piece of observation information falls within a linear scope based on the second piece of observation information; determining, by the verification system, that an effect resulting from the seeding experiment can be proved when the first piece of observation information falls within the linear scope based on the second piece of observation information, and deciding, by the verification system, that a cloud having a different feature flowed into at least one of the upwind area and the downwind area when the first piece of observation information and the second piece of observation information deviate from the linear scope. ### Claim 2 (depends on 1) The method of claim 1 wherein the observation information comprises vertical observation information and straight observation information. ### Claim 3 (depends on 1) The method of claim 1 wherein the aerial observation equipment comprises at least one of: an aerial data investigation system 118 (i.e., Aircraft Integrated Meteorological Measuring System-20, AIMMS-20); a water content measurement instrument (i.e., Multi-Element Water Content System, WCM-2000); a cloud particle combination measurement instrument (i.e., Cloud Combination Probe); and a precipitation particle measurement instrument (i.e., Precipitation Imaging Probe). ### Claim 4 A verification system of verifying an increase in precipitation, comprising: an aerial observation equipment configured to obtain a first piece of observation information from a upwind area and a second piece of observation information from a downwind area after a seeding experiment, the aerial observation equipment including a cloud condensation nucleus counter, a cloud combination probe, and a precipitation imaging probe, wherein the verification system is configured to spray artificial cloud seeds using an aircraft for the seeding experiment, wherein the verification system is configured to compare the first piece of observation information with the second piece of observation information so as to determine whether or not the first piece of observation information falls within a linear scope based on the second piece of observation information, and determine that an effect of the seeding experiment can be proved when the first piece of observation information falls within the linear scope based on the second piece of observation information, and wherein the verification system further decides that a cloud having a different feature flowed into at least one of the upwind area and the downwind area when the first piece of observation information deviates from the linear scope based on the second piece of observation information. ### Claim 5 (depends on 4) The system of claim 4 wherein the observation information comprises vertical observation information and straight observation information. ### Claim 6 (depends on 4) The system of claim 4 wherein the aerial observation equipment comprises at least one of: an aerial data investigation system (i.e., Aircraft Integrated Meteorological Measuring System-20), a water content measurement instrument (i.e., Multi-Element Water Content System); a cloud particle combination measurement instrument (i.e., Cloud Combination Probe); and a precipitation particle measurement instrument (i.e., Precipitation Imaging Probe). ### Claim 7 (depends on 4) The system of claim 4, wherein the verification system is further configured to quantify at least one of the first piece of observation information and the second piece of observation information. ### Claim 8 (depends on 7) The system of claim 7 wherein the verification system quantifies at least one of the first piece of observation information and the second piece of observation information at an average water concentration according to each size of cloud particles. ### Claim 9 (depends on 4) The system of claim 4, further comprising a seeding effect analyzer configured to analyze a seeding effect resulting from the seeding experiment.
