The movement of tropical cyclones (TCs), particularly around the time of landfall, can substantially affect the resulting damage. Recently, trends in TC translation speed and the likelihood of stalled TCs such as Harvey have received significant attention, but findings have remained inconclusive. Here, we examine how the June-September steering wind and translation speed of landfalling Texas TCs change in the future under anthropogenic climate change. Using several large-ensemble/multi-model datasets, we find pronounced regional variations in the meridional steering wind response over North America, but―consistently across models―stronger June-September-averaged northward steering winds over Texas. A cluster analysis of daily wind patterns shows more frequent circulation regimes that steer landfalling TCs northward in the future. Downscaling experiments show a 10-percentage-point shift from the slow-moving to the fast-moving end of the translation-speed distribution in the future. Together, these analyses indicate increases in the likelihood of faster-moving landfalling Texas TCs in the late 21^st century.

热带气旋（TC）的移动，尤其是在登陆时，会严重影响由此造成的破坏。近来，TC翻译速度的趋势以及诸如Harvey之类的陷入僵局的TC的可能性受到了极大的关注，但是研究结果仍然没有定论。在这里，我们研究了在人为气候变化的情况下，登陆的德克萨斯州TC的6月至9月的转向风和平移速度在未来如何变化。使用几个大型整体/多模型数据集，我们发现北美经向转向风响应中存在明显的区域变化，但在整个模型中一致的是，德克萨斯州6月至9月平均北向转向风更强。对每日风型的聚类分析显示，更频繁的环流状态使将来着陆的TC转向北方。缩小规模的实验表明，将来翻译速度分布的缓慢变化到快速变化之间将有10个百分点的变化。总之，这些分析表明，在21世纪后期，更快地登陆德克萨斯州TC的可能性会增加^圣世纪。
