The initial temperature of the land is 298K and the initial temperature of the sea is 293K. Here, the temperature was raised or lowered, keeping the temperature difference between the land and the sea constant at 10K. These are analyzed through penetration distance and duration.
1. Initial and Land +5K.
The above penetration graph shows that the sea breeze is stronger in the case of 'Land+5 K ' compared to the initial case.
Looking at the above duration graph, the duration of the sea breeze at 'Land+5K ' is shorter than the initial case. Therefore, it can be seen that the duration is shortened as the strength of the sea breeze becomes stronger.
In conclusion, if we raise the temperature of the land, we can see that the sea breeze is strong and the duration is shortened.
2. Initial and Land -15K
Before we analyze it, we expect that 'Land-15K' will have a shorter duration of sea breeze compared to the initial case.
However, as shown in the graph above, the duration of two cases were similar, unlike expected.
Also, the above graph shows that the sea breeze is weaker than the initial case.
In other words, if the strength of the sea breeze is weak, the duration is longer than expected.
3. Initial and Sea -5K
Before we analyze it, we predicted that the sea breeze would be long and the land breeze would be short because of the low sea temperature in this case.
However, as shown in the first graph, the duration of sea breeze was similar. Also, as shown in the two graphs below, the pattern of penetration was similar.
4. Initial and Sea +15K
In this case, it is also shown that 'Sea+15K' has a shorter duration of both winds and longer turning time compared to the initial case.
In the case of 'Sea+15K' penetration graph, the value was strange and difficult to analyze.
[Conclusion]
1. If the land temperature is higher at the same temperature range when looking at case 1 and 3, case 2 and 4, the wind strength will be strong and the duration of the sea breeze will be short.
2. The increase in temperature, as shown in case 1 and 4, affected the reduction in time of the sea breeze.
3. Reducing the temperature, as shown in case 2 and 3, is similar to the initial case of a sea breeze, but the strength of land breeze is significantly reduced.
4. In all four cases, the temperature difference of 10K compared to the difference of 5K in initial case, the turning time has been longer. In other words, the larger the temperature difference, the longer the turning time.
