Chemtrails Over Whangarei City On the 15th Of February, Followed By Strange Cloud Formations

At approximately 8.30am on Monday, the 15th of February, I looked up at the sky from Woodhill, which is a suburb of Whangarei, towards the Whangarei city centre and saw two distinct chemtrails, which are shown in the first three photographs below. In addition, there were what looked to be a number of aerosol trails which had been in the sky longer and had faded, which are shown in the subsequent photos. To view link here:

See the pictures of the strange cloud formations here. Ask yourself, does the wind cause distinct parallel lines to form in clouds like that, or is there an unnatural force at work?:
