    "abstract": "The day-night variation of cosmic rays intensity at sea level has been\nobserved by a simple G-M counter telescope. We preform two 5 hours counting\nduring the day and night and find that the pattern of variation is closely\nrelated to the atmospheric disturbance, especially when the observation station\nis being affected by meterological front or trough. Such effects may lasts for\na few days until the trough or fronts weakened. The pattern of variation may be\nnegatively correlated to the altitude of the 0 degC level of the atmosphere.\nThis is closely related to the muon decay effect in the atmosphere. The\nphenomenon should be further investigation for possible application in weather\nforecasting.",
