We explore a possibility that the daily sea-level pressure ( SLP ) over South Korea responds to the high-speed solar wind event .
This is of interest in two aspects : First , if there is a statistical association this can be another piece of evidence showing that various meteorological observables indeed respond to variations in the interplanetary environment .
Second , this can be a very crucial observational constraint since most models proposed so far are expected to preferentially work in higher latitude regions than the low latitude region studied here .
We have examined daily solar wind speed { V } , daily SLP difference { \Delta SLP } , and daily { \log ( BV ^ { 2 } ) } using the superposed epoch analysis in which the key date is set such that the daily solar wind speed exceeds 800 { kms ^ { -1 } } .
We find that the daily { \Delta SLP } averaged out of 12 events reaches its peak at day +1 and gradually decreases back to its normal level .
The amount of positive deviation of { \Delta SLP } is +2.5 hPa .
The duration of deviation is a few days .
We also find that { \Delta SLP } is well correlated with both the speed of solar wind and { \log ( BV ^ { 2 } ) } .
The obtained linear correlation coefficients and chance probabilities with one-day lag for two cases are r \simeq 0.81 with P > 99.9 \% , and r \simeq 0.84 with P > 99.9 \% , respectively .
We conclude by briefly discussing future direction to pursue .
