HTG Final results The spatial distributions of HTG at GPS stations at distinctive time epochs having a time interval of six h from 18:00 UTC, 9 August to 12:00 UTC, 11 August are presented in Figure 7. Colors with the arrow heads denote the magnitude of HTG (MHTG ) estimated following M HTG =2 G2 + GWE NS(five)plus the azimuth of HTG, , is determined by = atan( GNS ) GWE (6)Stations with MHTG smaller than three mm are certainly not shown in Figure five for the purpose of clarity. Most HTG arrows consistently point for the typhoon center using a magnitude larger than five mm as shown in Figure 5a when the Lekima created the first landfall around the mainland China, indicating a substantial horizontal asymmetry within the troposphere. The anomalous HTG for the duration of typhoon is contributed by each the hydrostatic gradient and water vapor-related wet gradient. Ref. [22] explained that the cyclone can induceRemote Sens. 2021, 13,ten ofsignificant air pressure gradients, and big tropospheric gradients appear perpendicular to the isobars, i.e., pointing to the cyclone center. On the other hand, the massive level of water vapor brought by the typhoon also lead to an apparent tropospheric gradient in the wet component, which can also be located in the PWV spatio-temporal variation evaluation in Section three. With all the moving on the typhoon, the path of HTG also alterations, nonetheless with arrows commonly pointing to the center from the typhoon as shown from Figure 7b , however the consistency Nitrocefin supplier amongst HTG at stations weakens compared with Figure 7a.Figure 7. Spatial distribution of HTG (color arrows) at UTC time (a) 09 August 18:00, (b) ten August 00:00, (c) 10 August 06:00, (d) ten August 12:00, (e) 10 August 18:00, (f) 11 August 00:00, (g) 11 August 06:00, and (h) 11 August 12:00. The center of Typhoon Lekima is marked (red symbol) in every panel.We also calculated the azimuth distinction at every station amongst the horizontal gradient vector as well as the path pointing in the station to the typhoon center. The distribution with the azimuth distinction with the epicentral distance are presented in Figures eight and 9 where the magnitude on the HTG is distinguished by the maker size and maker colour inside the scatter graphs. We are able to find that the probability for azimuth distinction smaller sized than 30 in Figure 9 is generally lower than probability in Figure eight, indicating that the HTG convergence phenomenon progressively weakened as the typhoon moved northward. At the early stage when the typhoon made a landfall, e.g., 18:00 UTC on 9 August, with maximum wind speed of 160.9 km/h, the probability of azimuth distinction smaller sized than 30 can attain practically 50 , as shown in Figure 8e. Additionally, most of stations with modest angular distinction are distributed around the typhoon center with distance of about 40000 km, as shown in each Figures 7a and 8a. Massive horizontal gradient is probably to take place at regions close for the edge on the typhoon. As the typhoon weakens, this particular distribution isn’t obvious. Hence, the distribution on the HTG direction can PK 11195 Epigenetics represent the passage and improvement on the typhoon in the early stages, and may be valuable for studying and detecting the typhoon.Remote Sens. 2021, 13,11 ofFigure eight.
