Based on records from wave gauges 3 and 7, we estimate the wave period for the leading wave group in the ship wake to be T [congruent to] 5.5 s for the outgoing and T [congruent to] 9 s for the ingoing track.
Though the use of wavelets will result in some time lag in identification (presumably up to the maximum wave period of 2 h), event identification even with a 2-h delay has the potential to be useful given that meteotsunami events often consist of multiple waves and can take substantial time to propagate along the coastline.
Data was retrospectively collected from Medical records of 520 patients received during the heat wave period. The extent of maximum temperature and heat index lasting during the heat wave period was retrieved from the Pakistan Metrological Department.4 The ethical review board approved the study (ERC number: 3752-EM-ERC-15).
Acute demand during extreme temperatures and heat wave periods present considerable challenges and is a growing concern for the healthcare system, especially the ED (Levy, Broccoli, Cole, Jenkins, & Klein, 2015).
Figure 9 shows the parametric curve corresponding to the data collected at a wave period of 1.54 s (0.65 Hz).
For the Marmara Sea, the significant wave height (H1/3) can be taken as 3.3 meters and the significant wave period (Ts) as 7.0 seconds (Atkins, 1996).
Specifically, they investigated the effect of wave height (in terms of wave steepness, [H.sub.s]/[L.sub.p], being [H.sub.s] the significant wave and [L.sub.p] the wavelength corresponding to the peak period), wave period (in terms of relative water depth, d/[L.sub.p]), and surf similarity parameter ([xi]) on the reflection coefficient ([K.sub.r]).
[11] develop a semiempirical function for significant wave height (Hs) and mean wave period (Tmw) retrieval from C-band VV polarization Sentinel-1 SAR.
We also did not consider the first day of a heat wave period as added temperature effect in order to only capture sustained heat effects over 2 or more days.

Influence of Wave Period. Cases with four periods of regular waves--2 s, 4 s, 6 s, and 8 s--are considered, while wave heights of regular waves and deploying velocity are determined as 2.5 m and 1 m/s, respectively.
